Negative contributions to entropy production induced by quantum coherences
Camille L. Latune, Ilya Sinayskiy, Francesco Petruccione
The entropy production in dissipative processes is the essence of the arrow of time and the second law of thermodynamics. For dissipation of quantum systems, it was recently shown…
Thermodynamics from indistinguishability: mitigating and amplifying the effects of the bath
Camille L. Latune, Ilya Sinayskiy, Francesco Petruccione
Rich quantum effects emerge when several quantum systems are indistinguishable from the point of view of the bath they interact with. In particular, delocalised excitations corresp…
Experimental investigation of Markovian and non-Markovian channel addition
S. A. Uriri, F. Wudarski, I. Sinayskiy +2
The study of memory effects in quantum channels helps in developing characterization methods for open quantum systems and strategies for quantum error correction. Two main sets of…
Lazy Open Quantum Walks
Garreth Kemp, Ilya Sinayskiy, Francesco Petruccione
Open quantum walks (OQWs) describe a quantum walker on an underlying graph whose dynamics is purely driven by dissipation and decoherence. Mathematically, they are formulated as co…
Heat flow reversals without reversing the arrow of time: the role of internal quantum coherences and correlations
Camille L. Latune, Ilya Sinayskiy, Francesco Petruccione
One of the stunning consequences of quantum correlations in thermodynamics is the reversal of the arrow of time, recently shown experimentally in [K. Micadei, et al., Nat. Commun.…
Energetic and entropic effects of bath-induced coherences
C. L. Latune, I. Sinayskiy, F. Petruccione
The unavoidable interaction of a quantum system with its surrounding (bath) is not always detrimental for quantum properties. For instance, under some specific conditions (that we…
Parallel quantum trajectories via forking for sampling without redundancy
Daniel K. Park, Ilya Sinayskiy, Mark Fingerhuth +2
The computational cost of preparing a quantum state can be substantial depending on the structure of data to be encoded. Many quantum algorithms require repeated sampling to find t…
