An almost convincing scheme for discriminating the preparation basis of quantum ensemble and why it will not work
Sandeep K Goyal, Rajeev Singh, Sibasish Ghosh
Mixed states of a quantum system, represented by density operators, can be decomposed as a statistical mixture of pure states in a number of ways where each decomposition can be vi…
Realization of arbitrary discrete unitary transformations using spatial and internal modes of light
Ish Dhand, Sandeep K. Goyal
Any lossless transformation on spatial and internal modes of light can be described by an unitary matrix, but there is no known proced…
Implementation of multidimensional quantum walks using linear optics and classical light
Sandeep K. Goyal, Filippus S. Roux, Andrew Forbes +1
Classical optics can be used to efficiently implement certain quantum information processing tasks with a high degree of control, for example, one-dimensional quantum walks through…
Process tomography via sequential measurements on a single quantum system
Humairah Bassa, Sandeep K. Goyal, Sujit K. Choudhary +3
We utilize a discrete (sequential) measurement protocol to investigate quantum process tomography of a single two-level quantum system, with an unknown initial state, undergoing Ra…
