Future quantum computers capable of solving relevant problems will require a large number of qubits that can be operated reliably1. However, the requirements of having a large qubit count and operating with high fidelity are typically conflicting. Spins in semiconductor quantu ...

Electrons and holes confined in quantum dots define excellent building blocks for quantum emergence, simulation, and computation. Silicon and germanium are compatible with standard semiconductor manufacturing and contain stable isotopes with zero nuclear spin, thereby serving ...

We demonstrate the strong coupling between a single electron spin in silicon and a single photon in a superconducting microwave cavity. Using the same cavity we perform rapid high-fidelity single-shot readout of two-electron spin states.

@enSilicon spin qubits are one of the leading platforms for quantum computation^{1,2}. As with any qubit implementation, a crucial requirement is the ability to measure individual quantum states rapidly and with high fidelity. Since the signal from a single electron spin

The requirements in quantum optics experiments for high single-photon detection efficiency, low timing jitter, low dark count rate and short dead time have been fulfilled with the development of superconducting nanowire single-photon detectors. Although they offer a detection ...

We experimentally investigate the performance of NbTiN superconducting nanowire single photon detectors above the base temperature of a conventional Gifford-McMahon cryocooler (2.5 K). By tailoring design and thickness (8 - 13 nm) of the detectors, high performance, high opera ...

### Rapid gate-based spin read-out in silicon using an on-chip resonator (Nature Nanotechnology, (2019), 14, 8, (742-746), 10.1038/s41565-019-0488-9)

In the version of this Letter originally published, the second, third and fourth exponential terms in equation (3) were incorrect; the corrected equation is shown below. (Formula presented.). The correct equation was used for data analysis. The online versions have been amende ...

Long coherence times of single spins in silicon quantum dots make these systems highly attractive for quantum computation, but how to scale up spin qubit systems remains an open question. As a first step to address this issue, we demonstrate the strong coupling of a single ele ...

Quantum computing holds the promise of exponential speedup compared to classical computing for select algorithms and applications. Relatively small numbers of logical quantum bits or qubits could outperform the largest of supercomputers. Quantum dots in Si-based heterostructur ...

Helium ion beam lithography (HIL) has been demonstrated as a promising alternative to electron beam lithography (EBL) for R&D purposes, offering high-resolution lithography at high pattern densities. This chapter reviews focused He ion beam lithography, providing a detaile ...
