Characterizing Photonic Partial Distinguishability Through Gram Matrix Tomography
Marcin Kotowski, Marco Robbio, Oliver Reardon-Smith +4
Partial distinguishability affects multiphoton interference, which is central to large-scale photonic experiments such as Boson Sampling and to applications of multiphoton states a…
Exponential lower bounds on the fermionic Gaussian rank of magic states and the bosonic coherent state rank of Fock states
Oliver Reardon-Smith
Recent algorithms for classical simulation of quantum mechanics have runtime whose superpolynomial component is given by a linear dependence on the number of terms required to writ…
Fast classical simulation algorithms for free-fermion dynamics with magic input
Jiwon Heo, Oliver Reardon-Smith, Michał Oszmaniec +2
The classical cost of simulating free-fermion (matchgate) circuits depends on both the input state and the computational task. We develop classical algorithms for circuits with non…
Classical simulation of free-fermionic dynamics and quantum chemistry with magic input
Changhun Oh, Michał Oszmaniec, Oliver Reardon-Smith +1
Establishing the precise computational boundary between classically tractable fermionic systems and those capable of genuine quantum advantage is a central challenge in quantum sim…
