Partitioned Quantum Subspace Expansion
Tom O'Leary, Lewis W. Anderson, Dieter Jaksch +1
We present an iterative generalisation of the quantum subspace expansion algorithm used with a Krylov basis. The iterative construction connects a sequence of subspaces via their l…

Solving lattice gauge theories using the quantum Krylov algorithm and qubitization
Lewis W. Anderson, Martin Kiffner, Tom O'Leary +2
Computing vacuum states of lattice gauge theories (LGTs) containing fermionic degrees of freedom can present significant challenges for classical computation using Monte-Carlo meth…
