New research post in Quantum Communications
Jun 22nd 2017
We are looking for an experienced and ambitious researcher with a background in quantum communications to join our team in one of the UK’s leading research intensive Universities, working on the UK Quantum Technology Hub for Quantum Communications.
Quantum key distribution (QKD) provides unbreakable, future-proof security against the vulnerabilities of most cryptosystems currently in operation. QKD has been implemented mostly over dedicated channels and between two parties. Before current communication vulnerabilities are exploited, it is essential to facilitate the use of QKD technology for any two users at any distance, via a network. This project addresses the theoretical analysis of quantum communications networks, including the UK Quantum Network, at access and metro levels. Another key aspect is the theoretical development of future generations of quantum networks via quantum repeaters.
Holding a PhD (or an expectation that a PhD will be awarded soon) in Physics, Engineering, or a related discipline, you will have a track record in quantum communications research which has led to publications in international refereed journals. You will also need to have experience in the use of numerical/symbolic maths software such as MATLAB, Maple, or Mathematica.
You will work closely with Dr M Razavi, at the intersection of quantum information science and optical communications. You will also collaborate with partner researchers in the National Hub for Quantum Communications Technologies.
You can download a copy of the candidate brief here. The deadline for applications is 12 July 2017.
To explore the post further or for any queries you may have, please contact: Dr Mohsen Razavi, Associate Professor (firstname.lastname@example.org)
ETSI/IQC Workshop on Quantum-Safe Cryptography, London, 13-15 September 2017
Jun 13th 2017
Following last year’s successful event at Toronto, Canada, the 5th ETSI/IQC workshop on quantum safe cryptography will take place this September in London, UK. The event is jointly co-organised by ETSI, the European Telecommunications Standards Institute, and the IQC, the University of Waterloo’s Institute of Quantum Computing, with further support provided by the Quantum Communications Hub, part of the UK National Quantum Technologies Programme. The National Cyber Security Centre and the CryptoWorks21 training partnership are also supporting partners.
The workshop is free of charge and structured along an executive (13/09) and technical (14-15/09) track. Focus on the first day will be on the potential of quantum computing and the technologies available to counteract subsequent threats to the existing cyber security infrastructure. Discussions during the following two days will focus on the current status of quantum-safe cryptography, the challenges of cryptographic standardisation on a global scale, the selection criteria for new encryption algorithms and specific government and industry requirements. Presentations have been invited on the following themes: global efforts and practical challenges on quantum-safe schemes; computational constraints and considerations for post-quantum cryptography and security from an industry perspective; high priority use cases for quantum-safe cryptography; standards for quantum cryptography devices and systems and for quantum-resistant public-key crypto algorithms; testing, metrics and certification for quantum-safety; new applications of post quantum crypto or quantum key distribution (QKD); attempts at cryptanalysis of new post-quantum systems; migration paths for post-quantum crypto and/or QKD. The full agenda is expected to become available by the end of June.

Establishing the boundaries of quantum secure communications
Apr 26th 2017
Today's classical communications, such as email or phone, are potentially vulnerable to eavesdroppers as conventional data encryption is based on the factorisation of large integers, an operation which is computationally hard on a classical computer but easily solvable on a quantum computer.
Recently, Google said that large quantum computers are only five years from commercial exploitability, therefore setting a deadline to current classical methods for private communication. Scientists say the solution comes from the field of quantum key distribution (QKD).
QKD uses particles, such as photons, to enable two remote parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt confidential messages. The security is not computational but based on a fundamental law of nature, the uncertainty principle.
Based on this idea, secure quantum networks are being built on a large scale in the UK and other countries, with China playing an important role and also leading the exploration of quantum satellite communication.
In such a scenario it is crucial to understand the ultimate limits of QKD, in terms of maximum rates, or capacities, at which two parties can distribute secret keys in a point-to-point connection.
In a paper published in Nature Communications scientists have established these capacities through the most important communication lines, including optical fibres.
Professor Stefano Pirandola of the University’s Department of Computer Science said: “This is a breakthrough result because it establishes the ultimate performance that any point-to-point protocol of QKD cannot surpass.
“Setting these limits is extremely important for both theoreticians and experimentalists, because they provide benchmarking for new theoretical protocols and actual experimental implementations.“
The study was funded by the EPSRC via the UK quantum communications hub.

More PhD studentships in quantum communications and post-post quantum cryptography projects!
Feb 10th 2017
The Quantum Communications Hub is providing financial support for a further three PhD studentships, two based at partner Heriot Watt University and one based at partner Royal Holloway, University of London.
The first available award is to work on an experimental project under the supervision of Professor Gerald Buller, based at Heriot-Watt’s quantum communications experimental group (http://www.single-photon.com). The PhD will involve experiments on quantum digital signatures, a new quantum communications protocol pioneered by Heriot-Watt in recent years. The group has conducted quantum digital signature experiments over significant lengths of optical fibre in both laboratory and installed settings and is now examining the possibility of applications using satellite communication systems. Consequently, some knowledge of free-space and/or optical fibre photonics would be beneficial. There are also opportunities to conduct additional work in related areas, such as coherent state amplifiers and 100 GHz optical code scrambling seeded using quantum encryption keys. The student will be involved in a wide range of research activities associated with the Quantum Communications Hub and gain invaluable experience and training in the fast-growing area of highly secure communications. The work will be primarily experimental, including operation of both the data-handling and quantum-optical aspects of major trials and demonstrations.
For more information, and to apply, please check this link.
This studentship is offered under the supervision of Professor Erika Andersson, who leads Heriot-Watt’s quantum information theory group. The PhD will involve work on quantum signatures, quantum measurements, and other topics in quantum communication. Previously, the group has introduced various practical ways of realising quantum signatures, and examined the security of these protocols. They have also worked e.g. on measurement-device independent quantum signatures, on quantum oblivious transfer, and on the use of different types of quantum amplifiers and quantum measurements for quantum communication. Experiments related to quantum signatures and quantum communication are also performed at Heriot-Watt, and there are excellent opportunities to work with experimentalists at Heriot-Watt and elsewhere. The student will be involved in a wide range of research activities associated with the Quantum Communications Hub and gain experience and training in the fast-growing area of highly secure communications. The work will be primarily theoretical, but opportunities to contribute to experimental work may exist, depending on the ability and interests of the successful applicant.
For more information and to apply, please see this link.
A further fully funded PhD/Doctoral studentship (with partial support from the Hub) is available at the Information Security Group of Royal Holloway (University of London) in the area of post-post quantum cryptography, under the supervision of Professor Ruediger Schack.
The ongoing development of quantum-computing technology poses a threat to the security of some widely used cryptographic schemes. Post-quantum cryptography responds to this threat by designing and analyzing schemes that are immune to attacks by an adversary assumed to be in possession of a quantum computer. The more recent field of post-post quantum cryptography assumes in addition that the adversary has full access to a quantum implementation of the encryption and/or decryption device, which implies that the adversary would be able to carry out a quantum superposition attack. This project will address some of the many open questions in post-post quantum cryptography. Possible directions for research include the development of formal security models and the cryptanalysis of a variety of cryptographic schemes under quantum superposition attacks. Another potential direction is the analysis of an in-between scenario where the adversary has full quantum-computing capabilities but only limited quantum access to the device, which is gaining importance with the increasing miniaturization of components.

New EPSRC-funded PhD studentship in Quantum Communication Networks!
Jan 13th 2017
Hub partners University of York and Toshiba Research Europe Ltd (TREL) Laboratories, based at Cambridge, are offering a fully funded EPSRC PhD studentship for research into quantum communication networks. The project will research the technology and applications for quantum communications that go beyond simple point to point networks. It will investigate methods for distributing quantum keys between arbitrary locations in different types of multi-nodal network, as well as develop applications exploiting network based key distribution.
Most work to date on quantum communications has focused on key distribution. Digital signatures are another very important cryptographic primitive used to protect electronic data from forgery. This project will develop GHz quantum communication hardware to implement new protocols for digital signatures, the security of which is based on the laws of nature. These are based upon sharing quantum correlations between three parties: Alice, Bob and Charlie. The quantum correlations can then be used by Alice to sign messages sent to Bob, the authenticity of which can be verified by Charlie and cannot be tampered with. The technology developed in the project will be implemented in the UK Quantum Network (UKQN) being set up by the Quantum Communications Hub. The UKQN comprises metropolitan quantum networks in Cambridge and Bristol that are connected by a backbone quantum link via London.
