This review describes recent groundbreaking results in Si, Si/SiGe, and dopant-based
quantum dots, and it highlights the remarkable advances in Si-based quantum physics that …

The efficiency of the future devices for quantum information processing is limited mostly by
the finite decoherence rates of the individual qubits and quantum gates. Recently …

The spin of an electron or a nucleus in a semiconductor naturally implements the unit of
quantum information—the qubit. In addition, because semiconductors are currently used in …

The size of silicon transistors used in microelectronic devices is shrinking to the level at
which quantum effects become important. Although this presents a significant challenge for …

We report on the noise spectrum experienced by few nanometer deep nitrogen-vacancy
centers in diamond as a function of depth, surface coating, magnetic field and temperature …

Sensitive nanoscale magnetic resonance imaging of target spins using nitrogen-vacancy
(NV) centers in diamond requires a quantitative understanding of dominant noise at the …

We present measurements of spin relaxation times (T 1, T 1 ρ, T 2) on very shallow (≲ 5 nm)
nitrogen-vacancy centers in high-purity diamond single crystals. We find a reduction of spin …

Quantum computers have the potential to efficiently solve problems in logistics, drug and
material design, finance, and cybersecurity. However, millions of qubits will be necessary for …

We investigate spin and optical properties of individual nitrogen vacancy centers located
within 1–10 nm from the diamond surface. We observe stable defects with a characteristic …

A qubit subjected to pure dephasing due to classical Gaussian noise can be turned into a
spectrometer of this noise by utilizing its readout under properly chosen dynamical …
