Energy efficiency of quantum computers
Miquel Carrasco-Codina, Pau Escofet, Paul Hilaire +13
How much energy does a quantum computer consume? Are they more efficient than their classical counterparts? In this work, we make a step towards answering these questions. We defin…
A Spin-Based Pathway to Testing the Quantum Nature of Gravity
Sougato Bose, Anupam Mazumdar, Roger Penrose +52
A key open problem in physics is the correct way to combine gravity (described by general relativity) with everything else (described by quantum mechanics). This problem suggests t…
Quantum Thermodynamics on a limit cycle
Varinder Singh, Euijoon Kwon, G J Milburn
We consider a periodic quantum clock based on cooperative resonance fluorescence at zero temperature. In the quantum case, this system has an exact steady state and the limit cycle…
Using coherent feedback for a periodic clock
Stefan Zeppetzauer, Leonardo Assis Morais, Xin He +2
A driven linear oscillator and a feedback mechanism are two necessary elements of any classical periodic clock. Here, we introduce a novel, fully quantum clock using a driven oscil…
