Universal Linear Optics
Jacques Carolan, Chris Harrold, Chris Sparrow +13
Linear optics underpins tests of fundamental quantum mechanics and computer science, as well as quantum technologies. Here we experimentally demonstrate the longstanding goal of a…
Heavy tails in the distribution of time-to-solution for classical and quantum annealing
Damian S. Steiger, Troels F. Rønnow, Matthias Troyer
For many optimization algorithms the time-to-solution depends not only on the problem size but also on the specific problem instance and may vary by many orders of magnitude. It is…
Reference frame independent quantum key distribution server with telecom tether for on-chip client
P. Zhang, K. Aungskunsiri, E. Martín-López +12
We demonstrate a client-server quantum key distribution (QKD) scheme, with large resources such as laser and detectors situated at the server-side, which is accessible via telecom-…
Calibration and High Fidelity Measurement of a Quantum Photonic Chip
H. W. Li, J. Wabnig, D. Bitauld +5
Integrated quantum photonic circuits are becoming increasingly complex. Accurate calibration of device parameters and detailed characterization of the prepared quantum states are c…
Demonstration of Free-space Reference Frame Independent Quantum Key Distribution
J. Wabnig, D. Bitauld, H. W. Li +3
Quantum key distribution (QKD) is moving from research laboratories towards applications. As computing becomes more mobile, cashless as well as cardless payment solutions are intro…
Reconfigurable controlled two-qubit operation on a quantum photonic chip
H. W. Li, S. Przeslak, A. O. Niskanen +7
Integrated quantum photonics is an appealing platform for quantum information processing, quantum communication and quantum metrology. In all these applications it is necessary not…
