Quantum Device Engineering Lab
Machine-translated · View original
A quantum device lab that manipulates electron spins in semiconductor quantum dots.
AboutAbout the lab
Controlling and reading out the spin of a single electron at will
The Quantum Device Engineering Lab studies quantum transport phenomena that occur in quantum structures such as semiconductor quantum dots.
The lab carries out experiments end to end, from fabricating nanometer-scale devices to measuring electrical conduction at cryogenic temperatures.
The spin of a single electron in a quantum dot offers excellent controllability and integrability, and is expected to be applied to quantum computers.
Toward the realization of semiconductor quantum computers, the lab develops key component technologies and works on large-scale integration of quantum dots.
Key terms
- Quantum dot
- A tiny semiconductor structure in which the motion of a single electron can be detected and the direction of its spin can be controlled
- Qubit
- The unit that carries information in a quantum computer. In this lab, the spin of a single electron in a quantum dot is used
- Superconducting proximity effect
- An effect in which diverse phenomena, such as Cooper pair splitting and the emergence of Majorana fermions, appear at a junction between a semiconductor and a superconductor

ResearchResearch themes
This lab studies how to manipulate and measure the spin of a single electron using semiconductor quantum dots, as well as devices that combine semiconductors and superconductors. Its goal is to realize a semiconductor quantum computer.
*Illustrative imageTwo-Dimensional Integration of Quantum Dots
Electron spins are promising as qubits with excellent controllability and integrability. A practical semiconductor quantum computer requires integrating many qubits, and arranging quantum dots in two dimensions is important for this. The lab studies the fabrication of two-dimensional quantum dot arrays and the manipulation and measurement of single electron spins.
*Illustrative imageSemiconductor-Superconductor Hybrid Devices
At junctions between semiconductors and superconductors, the superconducting proximity effect gives rise to diverse phenomena such as Cooper pair splitting and the emergence of Majorana fermions. Focusing on junctions between two-dimensional electron systems in semiconductors and superconductors, the lab fabricates devices that can be integrated and investigates new transport phenomena.
