Enhanced quantum thermometry near a dissipative phase transition in a driven Kerr cavity
Chayan Purkait, Bimalendu Deb
We investigate quantum thermometry in a driven--dissipative Kerr cavity coupled to a thermal reservoir. The system exhibits a finite-size precursor of a dissipative phase transitio…
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…
Ion-atom two-qubit quantum gate based on phonon blockade
Subhra Mudli, Bimalendu Deb
We theoretically demonstrate the universal two-qubit CNOT gate between an ionic and an atomic qubit relying on Rydberg excitation of the atom and the resulting phonon blockade in t…
Rydberg atom parity gate based on dark state resonances
Sinchan Snigdha Rej, Snigdhadev Ray, Bimalendu Deb
Quantum computation (QC) and digital quantum simulation (DQS) essentially require two- or multi-qubit controlled-NOT or -phase gates. We propose an alternative pathway for QC and D…
