Motion-Compensated Handheld Quantum Key Distribution System
Hyunchae Chun, Iris Choi, Grahame Faulkner +8
Mobile devices have become an inseparable part of our everyday life. They are used to transmit an ever-increasing amount of sensitive health, financial and personal information. Th…
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…
Electronic cooling of a submicron-sized metallic beam
J. T. Muhonen, A. O. Niskanen, M. Meschke +5
We demonstrate electronic cooling of a suspended AuPd island using superconductor-insulator-normal metal tunnel junctions. This was achieved by developing a simple fabrication meth…
Single artificial-atom lasing
O. Astafiev, K. Inomata, A. O. Niskanen +4
Solid-state superconducting circuits are versatile systems in which quantum states can be engineered and controlled. Recent progress in this area has opened up exciting possibiliti…
Electron-phonon coupling and longitudinal mechanical-mode cooling in a metallic nanowire
F. W. J. Hekking, A. O. Niskanen, J. P. Pekola
We investigate electron-phonon coupling in a narrow suspended metallic wire, in which the phonon modes are restricted to one dimension but the electrons behave three-dimensionally.…
Interqubit coupling mediated by a high-excitation-energy quantum object
S. Ashhab, A. O. Niskanen, K. Harrabi +6
We consider a system composed of two qubits and a high-excitation-energy quantum object used to mediate coupling between the qubits. We treat the entire system quantum mechanically…
