Coherent spin–photon coupling using a resonant exchange qubit
This work demonstrates strong coupling between single microwave photons in a niobium titanium nitride high-impedance resonator and a three-electron spin qubit in a gallium arsenide device consisting of three quantum dots.
Automated Tuning of Double Quantum Dots into Specific Charge States Using Neural Networks
While quantum dots are at the forefront of quantum device technology, tuning multi-dot systems requires a lengthy experimental process as multiple parameters need to be accurately controlled. This
Microwave Photon-Mediated Interactions between Semiconductor Qubits
The realization of a coherent interface between distant charge or spin qubits in semiconductor quantum dots is an open challenge for quantum information processing. Here we demonstrate both resonant
Virtual-photon-mediated spin-qubit–transmon coupling
Coherent coupling is demonstrated between a semiconductor spin qubit and a superconducting transmon in both resonant and dispersive regimes, where the interaction is mediated either by real or virtual resonator photons.
Coherent spin-qubit photon coupling
Electron spins hold great promise for quantum computation due to their long coherence times. An approach to realize interactions between distant spin-qubits is to use photons as carriers of quantum
Coherent microwave-photon-mediated coupling between a semiconductor and a superconducting qubit
Strong, coherent coupling between a semiconductor qubit and a superconducting qubit is demonstrated by using a high-impedance superconducted resonator as a quantum bus by Scarlino et al.
Floquet Spectroscopy of a Strongly Driven Quantum Dot Charge Qubit with a Microwave Resonator.
This work investigates a strongly driven GaAs double quantum dot charge qubit weakly coupled to a superconducting microwave resonator, showing distinct quantum features of multiphoton processes and a fringe pattern similar to Landau-Zener-Stückelberg interference.
Microwave-Cavity-Detected Spin Blockade in a Few-Electron Double Quantum Dot.
This work investigates Pauli spin blockade known from transport experiments at finite source-drain bias by coupling them to a magnetic field resilient NbTiN microwave resonator and finds an unconventional spin-blockade triggered by the absorption of resonator photons.
Coherent long-distance spin-qubit-transmon coupling
Spin qubits and superconducting qubits are among the promising candidates for a solid state quantum computer. For the implementation of a hybrid architecture which can profit from the advantages of
Strong photon coupling to the quadrupole moment of an electron in a solid-state qubit
The fundamental concept of light–matter interaction is routinely realized by coupling the quantized electric field in a cavity to the dipole moment of a real or an artificial atom. A recent proposal
