Quantum computers will be able to assume highly complex tasks in the future. With superconducting quantum processors, however, it has thus far been difficult to read out experimental results because ...

A research team has developed a new technique to rapidly and accurately determine the charge state of electrons confined in semiconductor quantum dots -- fundamental components of quantum computing ...

A sub-class of Si spin qubits uses metal-oxide-semiconductor (MOS) quantum dots to confine the electrons, a structure that ...

A 19th-century thought experiment, considered for decades to break the laws of thermodynamics, has been brought to life inside a quantum computer and used to charge a quantum battery. Physicist James ...

Above is a simulated charge sensor signal and its histogram. Below is a time integration that reduces noise and enables state identification (called threshold judgment, a conventional method). A ...
