Split spin-squeezed Bose-Einstein Condensates
Yumang Jing, Matteo Fadel, Valentin Ivannikov +1
We investigate and model the behaviour of split spin-squeezed Bose-Einstein condensates (BECs) system. In such a system, a spin-polarized BEC is first squeezed using a …
Covariance matrix entanglement criterion for an arbitrary set of operators
Vinay Tripathi, Chandrashekar Radhakrishnan, Tim Byrnes
We generalize entanglement detection with covariance matrices for an arbitrary set of observables. A generalized uncertainty relation is constructed using the covariance and commut…
Relativity of quantum states in entanglement swapping: Violation of Bell's inequality with no entanglement
Chris Nagele, Ebubechukwu O. Ilo-Okeke, Peter P. Rohde +2
The entanglement swapping protocol is analyzed in a relativistic setting, where shortly after the entanglement swapping is performed, a Bell violation measurement is performed. Fro…
A loophole-free Wheeler-delayed-choice experiment
H. -L. Huang, Y. -H. Luo, B. Bai +13
Wheeler's delayed-choice experiment investigates the indeterminacy of wave-particle duality and the role played by the measurement apparatus in quantum theory. Due to the inconsist…
Basis-independent quantum coherence and its distribution
Chandrashekar Radhakrishnan, Zhe Ding, Fazhan Shi +2
We analyze a basis-independent definition of quantum coherence. The maximally mixed state is used as the reference state, which allows for a way of defining coherence that is invar…
Generalized Grover's algorithm for multiple phase inversion states
Tim Byrnes, Gary Forster, Louis Tessler
Grover's algorithm is a quantum search algorithm that proceeds by repeated applications of the Grover operator and the Oracle until the state evolves to one of the target states. I…
