The Magic Scroll: Leveraging biased noise to improve magic state cultivation in register-based architectures
Ian D. Thorvaldson, Jeffrey Marshall, Jack R. Craig +3
Multiple quantum computing platforms across neutral atoms [1], nitrogen vacancy centres [2, 3], gate-defined dots [4-6] and 14|15 phosphorus atom qubits [7, 8] in silicon are exper…
Qudit Designs and Where to Find Them
Namit Anand, Jeffrey Marshall, Jason Saied +2
Unitary t-designs are some of the most versatile tools in quantum information theory. Their applications range from randomized benchmarking and shadow tomography, to more fundament…
Dual-unitary shadow tomography
Ahmed A. Akhtar, Namit Anand, Jeffrey Marshall +1
We introduce ``dual-unitary shadow tomography'' (DUST), a classical shadow tomography protocol based on dual-unitary brick-wall circuits. To quantify the performance of DUST, we st…
General protocols for the efficient distillation of indistinguishable photons
Jason Saied, Jeffrey Marshall, Namit Anand +1
We introduce state-of-the-art protocols to distill indistinguishable photons, reducing distinguishability error rates by a factor of , while using a modest amount of resources s…
Applications and resource estimates for open system simulation on a quantum computer
Evgeny Mozgunov, Jeffrey Marshall, Namit Anand
We present two applications where open system quantum simulation is the preferred approach on a quantum computer. We choose concrete parameters for the problems in such a way that…
