The strength of weak coupling
Alastair Kay, Christino Tamon
A paradoxical idea in quantum transport is that attaching weakly-coupled edges to a large base graph creates high-fidelity quantum state transfer. We provide a mathematical treatme…
Matrix Inversion by Quantum Walk
Alastair Kay, Christino Tamon
The HHL algorithm for matrix inversion is a landmark algorithm in quantum computation. Its ability to produce a state that is the solution of , given the input st…
Optimising Perfect Quantum State Transfer for Timing Insensitivity
Alastair Kay, Sooyeong Kim, Christino Tamon
When studying the perfect transfer of a quantum state from one site to another, it is typically assumed that one can receive the arriving state at a specific instant in time, with…
Local Realism of Macroscopic Correlations
Ravishankar Ramanathan, Tomasz Paterek, Alastair Kay +2
We show that for macroscopic measurements which cannot reveal full information about microscopic states of the system, the monogamy of Bell inequality violations present in quantum…
