Abstract Optimal generation of entangled states is critical significance for robust quantum information processing. An effective scheme presented speeding up the an state between a superconducting qubit and microwave photons via counterdiabatic driving. At magic bias point, first three levels charge‐phase circuit constitute qutrit. based on adiabatic population transfer achieved. By technique shortcuts to adiabaticity, driving applied qutrit, which then accelerates entanglement...
We present the prototype design for a novel user interface, which extends concept of tangible interfaces from mostly specialized hardware components and studio deployment to commodity mobile devices in daily life. Our enables be interface where each device can serve as both, touch sensing display item interaction. The only necessary modification is attachment conductive 2D pattern on device. Compared existing approaches, our Active Commodity Tangible User Interfaces (ACTUI) graphical output...
Optimal creation of photon Fock states is importance for quantum information processing and state engineering. Here an efficient strategy presented speeding up generation in a superconducting circuit via counterdiabatic driving. A transmon qubit dispersively coupled to quantized electrical field. We address Λ-configuration interaction between the composite system classical drivings. Based on two Gaussian-shaped drivings, single-photon can be generated adiabatically. Instead adding auxiliary...
Applying the transfer matrix and Green's function methods, we study valley-resolved transport properties of zigzag graphene nanoribbon (ZGNR) junctions. The width left right ZGNRs are NL NR, ≥ NR. step/dip positions conductance G, intravalley transmission coefficients (TKK ), valley polarization efficiency correspond to subband edges right/left ZGNR that controlled by NR/NL. intervalley ( ) exhibit peaks at most edge ZGNRs. In bulk gap ZGNR, =0, = ±1, is well preserved. As NR increases,...
Using the Green’s function method, we study modulation of conductance in zigzag graphene nanoribbon (ZGNR) junctions by gate voltages. As long as difference between voltages applied on left and right ZGNRs (ΔV) remains unchanged, profiles for different cases are exactly same, except to a displacement along EF-axis. It is found that transmission electrons from upper/lower edge state ZGNR lower/upper forbidden, therefore, width gap increases first then decreases |ΔV| increases. The states...

Entanglement generation via optimal drivings is of significance for quantum information science and engineering. Here, an efficient scheme proposed creating entangled states between two transmon qubits shortcuts to adiabaticity with constant Rabi drivings. Two three-level atoms Cooper-pair box circuits are coupled a common cavity field transmission-line resonator individually driven by adjustable classical microwaves. In the regime large detuning, we obtain effective three-state system...
