Thirty years after it was first proposed, quantum teleportation remains one of the most
important protocols in quantum information and quantum technologies, enabling the …

Quantum state preparation is an important subroutine for quantum computing. We show that
any n-qubit quantum state can be prepared with a Θ (n)-depth circuit using only single-and …

The standard primitives of quantum computing include deterministic unitary entangling
gates, which are not natural operations in many systems including photonics. Here, we …

Quantum technologies comprise an emerging class of devices capable of controlling
superposition and entanglement of quantum states of light or matter, to realize fundamental …

Qudit is a multi-level computational unit alternative to the conventional 2-level qubit.
Compared to qubit, qudit provides a larger state space to store and process information, and …

As we begin to reach the limits of classical computing, quantum computing has emerged as
a technology that has captured the imagination of the scientific world. While for many years …

Trapped ions are among the most promising systems for practical quantum computing (QC).
The basic requirements for universal QC have all been demonstrated with ions, and …

Photons have been a flagship system for studying quantum mechanics, advancing quantum
