Spin qubit systems are one of the promising candidates for quantum computing. The
quantum dot (QD) arrays are intensively investigated by many researchers. Because the …

This paper describes the current state of quantum computer development in the world
(including the hype) from three perspectives and introduces our research and development …

When a bug is detected by testing a quantum program on a quantum computer, we want to
determine its location to fix it. To locate the bug, the quantum program is divided into several …

In silicon quantum computers, a single electron is trapped in a microstructure called a
quantum dot, and its spin is used as a qubit. For large-scale integration of qubits, we …

Temperature rise of qubits due to heating is a critical issue in large-scale quantum
computers based on quantum-dot (QD) arrays. This leads to shorter coherence times …

The ability to transport single electrons on a quantum dot array dramatically increases the
freedom in designing quantum computation schemes that can be implemented on solid …

For the realization of large-scale quantum computers based on two-dimensional quantum
dot arrays in solid-state devices, technologies for the free transport of electrons on the arrays …
