Building a quantum computer that surpasses the computational power of its classical
counterpart is a great engineering challenge. Quantum software optimizations can provide …

STIRAP (stimulated Raman adiabatic passage) is a powerful laser-based method, usually
involving two photons, for efficient and selective transfer of populations between quantum …

Quantum computation is traditionally expressed in terms of quantum bits, or qubits. In this
work, we instead consider three-level qu trits. Past work with qutrits has demonstrated only …

Constructing a large-scale ion trap quantum processor will require entangling gate
operations that are robust in the presence of noise and experimental imperfection. We …

In this work, we put forward an approach of constructing the optimal composite pulse
sequence for robust population transfer in two-level systems. This approach is quite …

A highly efficient method for optical or microwave detection and separation of left-and right-
handed chiral molecules is proposed. The method utilizes a closed-loop three-state system …

Physical quantum systems are commonly composed of more than two levels and offer the
capacity to encode information in higher-dimensional spaces beyond the qubit, starting with …

The quantum coherent control of a quantum system with high fidelity is rather important in
quantum computation and quantum information processing. Many control techniques are …

Swept-frequency pulses have found applications in a wide range of areas including
spectroscopic techniques where efficient control of spins is required. For many of these …

Composite pulse sequences, which produce arbitrary predefined rotations of a qubit on the
Bloch sphere, are presented. The composite sequences contain up to 17 pulses and can …
