Universal quantum computation based on nanoelectromechanical systems
Physical Review Research, 2023 We propose to use a buckled plate as a qubit, where a double-well potential is mechanically produced by pushing the plate from both sides. The right and left positions of the plate are assigned to be quantum states |0〉 and |1〉.

Two-Qubit Pulse Gate for the Three-Electron Double Quantum Dot Qubit [PDF]
, 2015 The three-electron configuration of gate-defined double quantum dots encodes a promising qubit for quantum information processing. I propose a two-qubit entangling gate using a pulse-gated manipulation procedure.

Advanced Functional Materials, EarlyView.A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Non-adiabatic charge state transitions in singlet–triplet qubits
New Journal of Physics, 2013 In double quantum dot singlet–triplet qubits, the exchange interaction is used in both quantum gate operation and the measurement of the state of the qubit. The exchange can be controlled electronically by applying gate voltage pulses.

Training Optimization for Gate-Model Quantum Neural Networks [PDF]
Scientific Reports, 2019 Gate-based quantum computations represent an essential to realize near-term quantum computer architectures. A gate-model quantum neural network (QNN) is a QNN implemented on a gate-model quantum computer, realized via a set of unitaries with associated ...

Optimized Unconventional Geometric Gates in Superconducting Circuits
Applied Sciences, 2023 Nonadiabatic Abelian geometric quantum computation has been extensively studied, due to its fast manipulation and inherent noise resistance. However, to obtain the pure geometric phase, the quantum state is required to evolve along some special paths to ...

Advanced Functional Materials, EarlyView.Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.
