Journal ArticleDOI
Experimental Demonstration of Quantum Effects in the Operation of Microscopic Heat Engines.
J. Klatzow,Jonas Nils Becker,Patrick M. Ledingham,C. Weinzetl,Krzysztof T. Kaczmarek,Krzysztof T. Kaczmarek,Dylan J. Saunders,Joshua Nunn,Ian A. Walmsley,Raam Uzdin,Eilon Poem +10 more
TL;DR: Here, an ensemble of nitrogen vacancy centers in diamond is used for implementing two types of quantum heat engines, and the presence of such internal coherence causes different types of Quantum heat engines to become thermodynamically equivalent.
Journal ArticleDOI
Solid State Spin-Wave Quantum Memory for Time-Bin Qubits.
TL;DR: This device is the first demonstration of a quantum memory for time-bin qubits, with on-demand read-out of the stored quantum information, and represents an important step for the use of solid-state quantum memories in scalable quantum networks.
Journal ArticleDOI
Quantum storage of a photonic polarization qubit in a solid.
TL;DR: The storage capabilities of solid state quantum light matter interfaces to polarization encoding are extended, and the average conditional fidelity of the retrieved qubits exceeds 95% for a mean photon number μ=0.4.
Journal ArticleDOI
High-speed noise-free optical quantum memory
Krzysztof T. Kaczmarek,Patrick M. Ledingham,Benjamin Brecht,S. E. Thomas,S. E. Thomas,G. S. Thekkadath,G. S. Thekkadath,O. Lazo-Arjona,J. H. D. Munns,J. H. D. Munns,Eilon Poem,Amir Feizpour,Dylan J. Saunders,Joshua Nunn,Ian A. Walmsley +14 more
TL;DR: In this article, an intrinsically noise-free quantum memory protocol based on two-photon off-resonant cascaded absorption (ORCA) was proposed, which achieved successful storage of single photons in a warm atomic vapour with no added noise; confirmed by the unaltered photon number statistics upon recall.
Journal ArticleDOI
A cavity-enhanced room-temperature broadband Raman memory
Patrick M. Ledingham,J. H. D. Munns,S. E. Thomas,T. F. M. Champion,C. Qiu,Krzysztof T. Kaczmarek,Amir Feizpour,Eilon Poem,Ian A. Walmsley,Joshua Nunn,Dylan J. Saunders +10 more
TL;DR: A demonstration of a cavity-enhanced Raman memory is presented, showing suppression of four-wave mixing in quantum memories.
