Quantum Error Transmutation
Daniel Zhang, Toby Cubitt
We introduce a generalisation of quantum error correction, relaxing the requirement that a code should identify and correct a set of physical errors on the Hilbert space of a quant…
Dissipative Quantum Gibbs Sampling
Daniel Zhang, Jan Lukas Bosse, Toby Cubitt
Systems in thermal equilibrium at non-zero temperature are described by their Gibbs state. For classical many-body systems, the Metropolis-Hastings algorithm gives a Markov process…
Fitting time-dependent Markovian dynamics to noisy quantum channels
Emilio Onorati, Tamara Kohler, Toby S. Cubitt
Understanding how to characterise and mitigate errors is a key challenge in developing reliable quantum architecture for near-term applications. Recent work (arXiv:2103.17243) prov…
Dissipative ground state preparation and the Dissipative Quantum Eigensolver
Toby S. Cubitt
For any local Hamiltonian H, I construct a local CPT map and stopping condition which converges to the ground state subspace of H. Like any ground state preparation algorithm, this…
