with a focus on silicon quantum dots. Founded in April 2015, the company is leveraging its expertise to develop innovative solutions for industries ranging from semiconductor nanolithography to ...

Consumer electronic devices are made from materials that we have been using for more than 60 years, mainly silicon, germanium and ... Helmut Sondheimer. By quantum confinement, I refer to the ...

Abstract: We computationally investigate the programmability of quantum circuits that are manipulated with electron spins in semiconductor devices based on the silicon/silicon-germanium ...

Menno Veldhorst of QuTech in the Netherlands, who co-led this latest research, describes the architecture of the quantum dots. “First, we have a semiconductor heterostructure,” he explains, “This is ...

The shuttling experiments were performed in a 2 × 2 Ge quantum dot array using two-hole spin qubits. The device was fabricated on a strained Ge/silicon (Si)Ge heterostructure grown using chemical ...

The first part (chapter 3 and 4) reports the realization of two-dimensional quantum dot arrays in a silicon/silicon-germanium (Si/SiGe) and a germanium/silicon-germanium (Ge/SiGe) heterostructure.

In the original proposal of the so-called Loss-DiVincenzo qubit it was suggested to utilize the spin-1/2 degree of freedom of an electron confined in a quantum dot (QD) as a quantum mechanical ...

Germanium was actually discovered earlier than silicon as a useful semiconducting material in ... if engineered with gating structures connecting the layers. For example, quantum dots are ...
