Nature Communications, 2023 AbstractTopological phases of spin liquids with constrained disorder can host a kinetics of fractionalized excitations. However, spin-liquid phases with distinct kinetic regimes have proven difficult to observe experimentally. Here we present a realization of kagome spin ice in the superconducting qubits of a quantum annealer, and use it to demonstrate

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.

A Quantum Machine Learning Approach to Spatiotemporal Emission Modelling
Atmosphere, 2023 Despite the growing impact of emissions on our health and the environment, there remains an unmet need for emission concentration prediction and forecasting.

, 2005 We demonstrate that in a coupled two-qubit system any single-qubit gate can be decomposed into two conditional two-qubit gates and that any conditional two-qubit gate can be implemented by a manipulation analogous to that used for a controlled two-qubit ...

Multiparticle entanglement with quantum logic networks: Application to cold trapped ions [PDF]
, 2001 We show how to construct a multi-qubit control gate on a quantum register of an arbitrary size N. This gate performs a single-qubit operation on a specific qubit conditioned by the state of other N-1 qubits.

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.

Valence holes as Luttinger spinor based qubits in quantum dots
, 2009 We present a theory of valence holes as Luttinger spinor based qubits in p-doped self-assembled quantum dots within the 4-band $k\cdot p$ formalism. The two qubit levels are identified with the two chiralities of the doubly degenerate ground state.

Decoherence benchmarking of superconducting qubits [PDF]
, 2019 We benchmark the decoherence of superconducting qubits to examine the temporal stability of energy-relaxation and dephasing. By collecting statistics during measurements spanning multiple days, we find the mean parameters $\overline{T_{1}}$ = 49 $\mu$s ...

KUTRITE IN QUANTUM COMPUTATIONS
Современная наука и инновации, 2022 Limitations to the use of information and operation restriction information are a consequence of the physical nature of information. Conservative logic can solve any computable by Church, because with its help it is possible to implement a Turing machine

Quantum nondemolition measurements of a flux qubit coupled to a noisy detector
, 2011 We theoretically study the measurement-induced dephasing caused by back action noise in quantum nondemolition measurements of a superconducting flux qubit which is coupled to a superconducting quantum interference device (SQUID).
