Hyperradiance, photon blockade and concurrence in a pair of qubits inside a driven cavity
Anushree Dey, Bimalendu Deb
We theoretically study the radiance properties of a pair of qubits inside a single-mode cavity driven by a two-photon drive. Our results show that, when the two qubits are strongly…
Controlling correlations of a polaritonic Luttinger liquid by engineered cross-Kerr nonlinearity
Nabaneet Sharma, Anushree Dey, Bimalendu Deb
We study correlation properties of polaritons at zero temperature in a multiconnected Jaynes--Cummings (MCJC) lattice on a superconducting circuit quantum electrodynamics platform…
Dynamic structure factor of a driven-dissipative Bose-Hubbard model
Subhanka Mal, Anushree Dey, Kingshuk Adikary +1
Dynamic structure factor (DSF) is important for understanding excitations in many-body physics; it reveals information about the spectral and spatial correlations of fluctuations i…
Ion-mediated interaction and controlled phase gate operation between two atomic qubits
Subhra Mudli, Subhanka Mal, Sinchan Snigdha Rej +2
We propose a toy model of ion-atom hybrid quantum system for quantum computing. We show that when two atomic qubits in two largely separated optical tweezers interact with a single…
