Benchmarking exchange-only control of a 48-spin singlet manifold
HRL Quantum Team, Microsoft Collaborators, : +125
Exchange-only quantum computing benefits from high fidelity and straightforward control afforded by the exchange interaction. However, independently controllable qubits must be enc…
Spin singlets are useful
Silas Hoffman, Edward H. Chen, Matthew Brooks +6
We evaluate the utility of the spin-zero manifold of an exchange-coupled array of spins for tasks in quantum computation and quantum simulation. Since pairs of electrons can be…
Gate-dependent offset charge shifts and anharmonicity in gatemon qubits in the weak tunneling regime
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Gatemon qubits are based on a superconductor-quantum dot-superconductor (S-QD-S) junction which enables in situ electrostatic tuning via a gate electrode. For a single-channel QD t…
Resolving Andreev spin qubits in germanium-based Josephson junctions
Silas Hoffman, Charles Tahan
Andreev spin qubits (ASQs) are a promising platform for quantum information processing which benefit from both the small footprint of semiconducting spin qubits and the long range…
Quantum Intuition XR: Tangible Quantum Mechanics using Interactive XR Experience
Jamie Ngoc Dinh, Marven Wong, Matthew Brooks +2
Understanding quantum mechanics is inherently challenging due to its counterintuitive principles. Quantum Intuition XR is an interactive, extended reality (XR) experience designed…
Simulated Non-Abelian Statistics of Majorana Zero Modes from a Kitaev Lattice
Foster Sabatino, Matthew Brooks, Charles Tahan +1
We simulate the non-Abelian exchange of Majorana zero modes (MZMs) on a quantum computer. Rather than utilizing MZMs at the boundaries of quantum Ising chains, which are typically…
Measurement-based Simulation of Geometric Gates in Topological Qubits on NISQ Devices
Matthew Brooks, Foster Sabatino, Charles Tahan +1
While the adiabatic exchange of Majorana zero modes (MZMs) enables a non-universal set of geometrically protected gates, realising an experimental implementation of MZM braiding re…
