Variational Gibbs State Preparation on Trapped-Ion Devices
Reece Robertson, Mirko Consiglio, Josey Stevens +3
We implement a variational quantum algorithm for Gibbs state preparation of a transverse-field Ising model on IonQ's quantum computers. To this end, we train the variational parame…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
From compatibility of measurements to exploring Quantum Darwinism on NISQ
Emery Doucet, Sebastian Deffner
Quantum Darwinism explains how tenets of classical reality, such as objectivity and repeatability, emerge within a quantum universe. As a mathematical framework, Quantum Darwinism…
Thermodynamic significance of QUBO encoding on quantum annealers
Emery Doucet, Zakaria Mzaouali, Reece Robertson +3
Quadratic unconstrained binary optimization (QUBO) is the standard interface to quantum annealers, yet a single constrained task admits many QUBO encodings whose penalty choices re…
Information Processing in Quantum Thermodynamic Systems: an Autonomous Hamiltonian Approach
Shou-I Tang, Emery Doucet, Akram Touil +2
Extending the quantum formulation of [Phys. Rev. X 3, 041003 (2013)] to a more general setting for studying the thermodynamics of information processing including initial correlati…
On the Baltimore Light RailLink into the quantum future
Krzysztof Domino, Emery Doucet, Reece Robertson +2
In the current era of noisy intermediate-scale quantum (NISQ) technology, quantum devices present new avenues for addressing complex, real-world challenges including potentially NP…
