The improvements to qubit device yield combined with the high ... Researchers also found that single-electron devices from these wafers perform well when operated as spin qubits, achieving 99.9 ...

consisting of a single-qubit operation and a two-qubit operation. All quantum operations can be realized by combining elements of the universal operations. *2 Electron spin Internal degrees of freedom ...

known as qubit systems. In one such system, solid host materials like diamond or moissanite retain quantum information ...

PI: Prof. Jonathan Hood (Purdue University) Prototypical quantum processors based on electron-on-solid-neon (eNe) qubits Motivation: We recently realized a new solid-state qubit platform by trapping ...

An international research team led by QuTech has realized a three-site Kitaev chain using semiconducting quantum dots coupled by superconducting segments in a hybrid InSb/Al nanowire. When comparing ...

To achieve high-performance hot silicon qubits, we are exploring the "sweet spot" where quantum coherence time is maximized and comparing electron spin and hole spin systems. Figure 1: Implementation ...

Carbon's allotropes, like graphene and nanotubes, offer superior properties for quantum computing, driving energy efficiency ...

Full electrical isolation, with manipulation through capacitive coupling, said the lab, contributes to the long coherence time which would be compromised by direct electrical connections to the qubit ...

Majorana qubits could be error resistant. But after a contentious talk at the Global Physics Summit, scientists aren’t convinced Microsoft has them.

Physicists continue to argue over Microsoft’s qubit claims. The entire field hangs in a delicate balance.
