Quantum energetics of a non-commuting measurement
Xiayu Linpeng, Nicolò Piccione, Maria Maffei +5
When a measurement observable does not commute with a quantum system's Hamiltonian, the energy of the measured system is typically not conserved during the measurement. Instead, en…
Fundamental mechanisms of energy exchanges in autonomous measurements based on dispersive qubit-light interaction
Nicolò Piccione, Maria Maffei, Xiayu Linpeng +3
Measuring an observable which does not commute with the Hamiltonian of a quantum system usually modifies the mean energy of this system. In an autonomous measurement scheme, coupli…
On-demand driven dissipation for cavity reset and cooling
Vivek Maurya, Haimeng Zhang, Daria Kowsari +9
We present a superconducting circuit device that provides active, on-demand, tunable dissipation on a target mode of the electromagnetic field. Our device is based on a tunable "di…
Chiral Bell-state transfer via dissipative Liouvillian dynamics
Shishir Khandelwal, Weijian Chen, Kater W. Murch +1
Chiral state transfer along closed loops in the vicinity of an exceptional point is one of the many counter-intuitive observations in non-Hermitian physics. The application of this…
Constraining work fluctuations of non-Hermitian dynamics across the exceptional point of a superconducting qubit
Serra Erdamar, Maryam Abbasi, Byung Ha +4
Thermodynamics constrains changes to the energy of a system, both deliberate and random, via its first and second laws. When the system is not in equilibrium, fluctuation theorems…
Superconducting Non-Reciprocity Based on Time-Modulated Coupled-Resonator Systems
Yi Zhuang, Chandrashekhar Gaikwad, Daria Kowsari +2
We present a unified approach for designing a diverse range of superconducting non-reciprocal components, including circulators, isolators, and uni-directional amplifiers, based on…
