The first realization of nuclear spin qubit control in two-dimensional materials may expand the frontier of quantum science and technology

According to a paper published in "Nature Materials" on the 15th, researchers at Purdue University in the United States have achieved the realization of the nuclear spin in two-dimensional (2D) materials by using photon and electron spin qubits to control the nuclear spin in two-dimensional (2D) materials.

The researchers say this is the first work to demonstrate optical initialization and coherent control of nuclear spins in 2D materials

Spin qubits can be used as sensors, for example to probe the structure of proteins, or to probe the temperature of a target with nanoscale resolution

This time, the research team created an interface between photons and nuclear spins in ultrathin hexagonal boron nitride

The nuclear spin can be optically initialized—set to a known spin—by ​​the surrounding electron spin qubits

The researchers say the 2D nuclear spin lattice is suitable for large-scale quantum simulations

The researchers used a laser to pump the electrons to a spin state of zero, which has a negligible effect on the spin of the nitrogen nucleus
