A quantum Stirling heat engine operating in finite time
Debmalya Das, George Thomas, Andrew N. Jordan
In a quantum Stirling heat engine, the heat exchanged with two thermal baths is partly utilized for performing work by redistributing the energy levels of the working substance. We…
Programmable Heisenberg interactions between Floquet qubits
Long B. Nguyen, Yosep Kim, Akel Hashim +9
The fundamental trade-off between robustness and tunability is a central challenge in the pursuit of quantum simulation and fault-tolerant quantum computation. In particular, many…
Time-Dependent Hamiltonian Reconstruction using Continuous Weak Measurements
Karthik Siva, Gerwin Koolstra, John Steinmetz +9
Reconstructing the Hamiltonian of a quantum system is an essential task for characterizing and certifying quantum processors and simulators. Existing techniques either rely on proj…
Isolating noise and amplifying signal with quantum Cheshire cat
Ahana Ghoshal, Soham Sau, Debmalya Das +1
The so-called quantum Cheshire cat is a phenomenon in which an object, identified with a "cat", is dissociated from a property of the object, identified with the "grin" of the cat.…
Continuous measurement of a qudit using dispersively coupled radiation
John Steinmetz, Debmalya Das, Irfan Siddiqi +1
We analyze the continuous monitoring of a qudit coupled to a cavity using both phase-preserving and phase-sensitive amplification. The quantum trajectories of the system are descri…
Delayed choice of paths selected by grin and snarl of quantum Cheshire Cat
Debmalya Das, Ujjwal Sen
The so-called quantum Cheshire Cat is a scenario where a photon, identified with a cat, and a component of its polarization, identified with the grin of that cat, are separated. We…
