Supercatalysis
Somshubhro Bandyopadhyay, Vwani Roychowdhury
We show that entanglement-assisted transformations of bipartite entangled states can be more efficient than catalysis [D. Jonathan and M. B. Plenio, Phys. Rev. Lett. 83, 3566 (1999…
Partial recovery of entanglement in bipartite entanglement transformations
Somshubhro Bandyopadhyay, Vwani Roychowdhury, Farrokh Vatan
Any deterministic bipartite entanglement transformation involving finite copies of pure states and carried out using local operations and classical communication (LOCC) results in…
A new proof for the existence of mutually unbiased bases
Somshubhro Bandyopadhyay, P. Oscar Boykin, Vwani Roychowdhury +1
We develop a strong connection between maximally commuting bases of orthogonal unitary matrices and mutually unbiased bases. A necessary condition of the existence of mutually unbi…
Quantum Supearrivals
S. Bandyopadhyay, A. S. Majumdar, D. Home
A curious effect is uncovered by calculating the it time evolving probability of reflection of a Gaussian wave packet from a rectangular potential barrier while it is perturbed by…
