Fast forward to the classical adiabatic invariant
Christopher Jarzynski, Sebastian Deffner, Ayoti Patra +1
We show how the classical action, an adiabatic invariant, can be preserved under non-adiabatic conditions. Specifically, for a time-dependent Hamiltonian in o…
Demonstration of entanglement assisted invariance on IBM's Quantum Experience
Sebastian Deffner
Quantum entanglement is among the most fundamental, yet from classical intuition also most surprising properties of the fully quantum nature of physical reality. We report several…
Trade-off between speed and cost in shortcuts to adiabaticity
Steve Campbell, Sebastian Deffner
Achieving effectively adiabatic dynamics is a ubiquitous goal in almost all areas of quantum physics. Here, we study the speed with which a quantum system can be driven when employ…
-symmetric slowing-down of decoherence
Bartłomiej Gardas, Sebastian Deffner, Avadh Saxena
We investigate -symmetric quantum systems ultra-weakly coupled to an environment. We find that such open systems evolve under -symme…
Quantum work and the thermodynamic cost of quantum measurements
Sebastian Deffner, Juan Pablo Paz, Wojciech H. Zurek
Quantum work is usually determined from two projective measurements of the energy at the beginning and at the end of a thermodynamic process. However, this paradigm cannot be consi…
Repeatability of measurements: Equivalence of hermitian and non-hermitian observables
Bartłomiej Gardas, Sebastian Deffner, Avadh Saxena
A non-commuting measurement transfers, via the apparatus, information encoded in a system's state to the external "observer". Classical measurements determine properties of physica…
