Quantum phase estimation in presence of glassy disorder
Soubhadra Maiti, Kornikar Sen, Ujjwal Sen
We investigate the response to noise, in the form of glassy disorder present in circuit elements, in the success probability of the quantum phase estimation algorithm, a subroutine…
Response to glassy disorder in coin on spread of quantum walker
Priya Ghosh, Kornikar Sen, Ujjwal Sen
We analyze the response to incorporation of glassy disorder in the coin operation of a discrete-time quantum walk in one dimension. We find that the ballistic spread of the disorde…
Quantum coherence with incomplete set of pointers and corresponding wave-particle duality
Ingita Banerjee, Kornikar Sen, Chirag Srivastava +1
Quantum coherence quantifies the amount of superposition in a quantum system, and is the reason and resource behind several phenomena and technologies. It depends on the natural ba…
Measurement-device-independent nonlinear entanglement witnesses
Kornikar Sen, Chirag Srivastava, Ujjwal Sen
Entanglement witnesses are one of the most effective methods to detect entanglement. It is known that nonlinear entanglement witnesses provide better entanglement detection than th…
