On the qubit routing problem [PDF]
arXiv: Quantum Physics, 2019 We introduce a new architecture-agnostic methodology for mapping abstract quantum circuits to realistic quantum computing devices with restricted qubit connectivity, as implemented by Cambridge Quantum Computing's tket compiler. We present empirical results showing the effectiveness of this method in terms of reducing two-qubit gate depth and two-qubit

Demonstrating a Continuous Set of Two-Qubit Gates for Near-Term Quantum Algorithms. [PDF]
Physical Review Letters, 2020 Quantum algorithms offer a dramatic speedup for computational problems in material science and chemistry. However, any near-term realizations of these algorithms will need to be optimized to fit within the finite resources offered by existing noisy ...

Physics Letters B, 2010 We show that qubit and chirotope concepts are closely related. In fact, we prove that the qubit concept leads to a generalization of the chirotope concept, which we call qubitope. Moreover, we argue that a possible qubitope theory may suggest interesting applications of oriented matroid theory in at least three physical contexts, in which qubits make ...

Observation of a many-body dynamical phase transition with a 53-qubit quantum simulator [PDF]
Nature, 2017 A quantum simulator is a type of quantum computer that controls the interactions between quantum bits (or qubits) in a way that can be mapped to certain quantum many-body problems.

Readout of Majorana qubits [PDF]
Physical Review Research, 2020 Schemes for topological quantum computation with Majorana bound states rely heavily on the ability to projectively measure products of Majorana operators. Here, we employ Markovian quantum measurement theory, including the readout device, to analyze such measurements.

Quantum state estimation when qubits are lost: a no-data-left-behind approach
New Journal of Physics, 2017 We present an approach to Bayesian mean estimation of quantum states using hyperspherical parametrization and an experiment-specific likelihood which allows utilization of all available data, even when qubits are lost.

Nature Communications, 2023 AbstractCavity quantum electrodynamics (QED) uses a cavity to engineer the mode structure of the vacuum electromagnetic field such as to enhance the interaction between light and matter. Exploiting these ideas in solid-state systems has lead to circuit QED which has emerged as a valuable tool to explore the rich physics of quantum optics and as a ...

Phonon-induced decoherence of a charge quadrupole qubit
New Journal of Physics, 2018 Many quantum dot qubits operate in regimes where the energy splittings between qubit states are large and phonons can be the dominant source of decoherence.
