Researchers Design Triple Quantum Dot for Quantum Information Applications

Abstract:
While quantum dots have existed since the 1980s, only in the past decade have physicists successfully created lateral few-electron single quantum dots. These quantum dots enable physicists to manipulate quantum spins, which could be used as qubits for quantum information applications. Along these lines, a team of physicists from the National Research Council in Canada who were responsible for the original lateral few-electron single quantum dot have recently designed a new few-electron triple quantum dot circuit, and demonstrated that all three quantum dots can be tuned in resonance.
