Single photonic qutrit in a collective Rydberg polariton
Yuechun Jiao, Oliver D. W. Hughes, Max Z. Festenstein +5
We report on the coherent creation, control and read-out of a single photonic qutrit in a Rydberg ensemble. In each measurement, an optical photon is stored as a Rydberg polariton…
All non-Gaussian states are advantageous for channel discrimination: Robustness of non-convex continuous variable quantum resources
Leah Turner, Madalin Guta, Gerardo Adesso
Which quantum phenomena are advantageous for information processing tasks? By classifying quantum states as resourceful versus non-resourceful, or free, the mathematical formalism…
Exact Model Reduction for Continuous-Time Open Quantum Dynamics
Tommaso Grigoletto, Yukuan Tao, Francesco Ticozzi +1
We consider finite-dimensional many-body quantum systems described by time-independent Hamiltonians and Markovian master equations, and present a systematic method for constructing…
Spin Phonon Relaxation Dynamics from a Conical Intersection of Trapped Rydberg Ions
Manish Chaudhary, Rejish Nath, Weibin Li
Non-adiabatic processes near conical intersections are rooted in the stronger coupling between electronic and nuclear degrees of freedom. Using a system of two trapped Rydberg ions…
Quantum processes as thermodynamic resources: the role of non-Markovianity
Guilherme Zambon, Gerardo Adesso
Quantum thermodynamics studies how quantum systems and operations may be exploited as sources of work to perform useful thermodynamic tasks. In real-world conditions, the evolution…
Thermodynamics of coupled time crystals with an application to energy storage
Paulo J. Paulino, Albert Cabot, Gabriele De Chiara +3
Open many-body quantum systems can exhibit intriguing nonequilibrium phases of matter, such as time crystals. In these phases, the state of the system spontaneously breaks the time…
