Practical limitations of quantum data propagation on noisy quantum processors
Gaurav Saxena, Ahmed Shalabi, Thi Ha Kyaw
The variational quantum imaginary time evolution algorithm is efficient in finding the ground state of a quantum Hamiltonian. This algorithm involves solving a system of linear equ…
Multiphoton Bell-type inequality: a tool to unearth nonlocality of continuous variable quantum optical systems
Chandan Kumar, Gaurav Saxena, Arvind
We consider a multiphoton Bell-type inequality to study nonlocality in four-mode continuous variable systems, which goes beyond two-photon states and can be applied to mixed as wel…
Dynamical Resource Theory of Quantum Coherence
Gaurav Saxena, Eric Chitambar, Gilad Gour
Decoherence is all around us. Every quantum system that interacts with the environment is doomed to decohere. The preservation of quantum coherence is one of the major challenges f…
Frequency Stability of Atomic Frequency Standards beyond Quantum Projection Noise
G. M. Saxena
In this paper we describe that the optically pumped frequency standards can have frequency stability beyond the quantum noise limit by detecting the Ramsey resonance through the sq…
Noisy quadrature of squeezed light and laser cooling
G. M. Saxena, A. Agarwal
The laser cooling of atoms is a result of the combined effect of doppler shift, light shift and polarization gradient. These are basically undesirable phenomena. However, they comb…
Inverse operator representations of quantum phase
G. M. Saxena
We define quantum phase in terms of inverses of annihilation and creation operators. We show that like Susskind - Glogower phase operators, the measured phase operators and the uni…
