  • The Case for Quantum Key Distribution
    The Case for Quantum Key Distribution Douglas Stebila1, Michele Mosca2,3,4, and Norbert Lütkenhaus2,4,5 1 Information Security Institute, Queensland University of Technology, Brisbane, Australia 2 Institute for Quantum Computing, University of Waterloo 3 Dept. of Combinatorics & Optimization, University of Waterloo 4 Perimeter Institute for Theoretical Physics 5 Dept. of Physics & Astronomy, University of Waterloo Waterloo, Ontario, Canada Email: [email protected], [email protected], [email protected] December 2, 2009 Abstract Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures. It can provide long-term confidentiality for encrypted information without reliance on computational assumptions. Although QKD still requires authentication to prevent man-in-the-middle attacks, it can make use of either information-theoretically secure symmetric key authentication or computationally secure public key authentication: even when using public key authentication, we argue that QKD still offers stronger security than classical key agreement. 1 Introduction Since its discovery, the field of quantum cryptography — and in particular, quantum key distribution (QKD) — has garnered widespread technical and popular interest. The promise of “unconditional security” has brought public interest, but the often unbridled optimism expressed for this field has also spawned criticism and analysis [Sch03, PPS04, Sch07, Sch08]. QKD is a new tool in the cryptographer’s toolbox: it allows for secure key agreement over an untrusted channel where the output key is entirely independent from any input value, a task that is impossible using classical1 cryptography. QKD does not eliminate the need for other cryptographic primitives, such as authentication, but it can be used to build systems with new security properties.

    Experimental Single-Copy Entanglement Distillation Sebastian Ecker,1, 2, ∗ Philipp Sohr,1, 2 Lukas Bulla,1, 2 Marcus Huber,1, 3 Martin Bohmann,1, 2 and Rupert Ursin1, 2, y 1Institute for Quantum Optics and Quantum Information (IQOQI), Austrian Academy of Sciences, Boltzmanngasse 3, 1090 Vienna, Austria 2Vienna Center for Quantum Science and Technology (VCQ), Faculty of Physics, University of Vienna, Boltzmanngasse 5, 1090 Vienna, Austria 3Institute for Atomic and Subatomic Physics, Vienna University of Technology, 1020 Vienna, Austria The phenomenon of entanglement marks one of the furthest departures from classical physics and is indispensable for quantum information processing. Despite its fundamental importance, the distribution of entanglement over long distances through photons is unfortunately hindered by unavoidable decoherence effects. Entanglement distillation is a means of restoring the quality of such diluted entanglement by concentrating it into a pair of qubits. Conventionally, this would be done by distributing multiple photon pairs and distilling the entanglement into a single pair. Here, we turn around this paradigm by utilising pairs of single photons entangled in multiple degrees of freedom. Specifically, we make use of the polarisation and the energy-time domain of photons, both of which are extensively field-tested. We experimentally chart the domain of distillable states and achieve relative fidelity gains up to 13.8 %. Compared to the two-copy scheme, the distillation rate of our single-copy scheme is several orders of magnitude higher, paving the way towards high-capacity and noise-resilient quantum networks. Entanglement lies at the heart of quantum physics, two-photon CNOT gate cannot be deterministically re- reflecting the quantum superposition principle between alised with passive linear optics [19{22].
