Quantum computers have made extraordinary progress over the past decade, and
significant milestones have been achieved along the path of pursuing universal fault-tolerant …

The efficient control of a large number of qubits is one of the most challenging aspects for
practical quantum computing. Current approaches in solid-state quantum technology are …

The possibility of engineering artificial Kitaev chains in arrays of quantum dots coupled via
narrow superconducting regions has emerged as an attractive way to overcome the disorder …

The robustness of the macroscopic quantum nature of a superconductor can be
characterized by the superfluid stiffness, ρ s, a quantity that describes the energy required to …

Three key metrics for readout systems in quantum processors are measurement speed,
fidelity, and footprint. Fast high-fidelity readout enables midcircuit measurements, a …

Nonpolar atoms or molecules with low particle mass and weak inter-particle interactions can
form quantum liquids and solids (QLS) at low temperatures. Excess electrons naturally bind …

Optimal control of qubits requires the ability to adapt continuously to their ever-changing
environment. We demonstrate a real-time control protocol for a two-electron singlet-triplet …

In a recent breakthrough experiment [Nature (London) 614, 445 (2023) 10.1038/s41586-022-
05585-1], signatures of Majorana zero modes have been observed in tunnel spectroscopy …

As quantum processors grow in complexity, new challenges arise such as the management
of device variability and the interface with supporting electronics. Spin qubits in silicon …

Majorana bound states (MBSs) are quasiparticles that are their own antiparticles. They are
predicted to emerge as zero-energy modes localized at the boundary of a topological …
