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

Controlling and programming quantum devices to process quantum information by the unit
of quantum dit, ie, qudit, provides the possibilities for noise-resilient quantum …

This study reviews the recent progress of high-dimensional quantum information processing
with photons. We first introduce the basic language of high-dimensional quantum …

Complex forms of quantum entanglement can arise in two qualitatively different ways: either
between many qubits or between two particles with higher-than-qubit dimension. While both …

Quantum speed limits set the maximal pace of state evolution. Two well-known limits exist
for a unitary time-independent Hamiltonian: the Mandelstam-Tamm and Margolus-Levitin …

Quantum machine learning is the field that aims to integrate machine learning with quantum
computation. In recent years, the field has emerged as an active research area with the …

Gate-based quantum computers typically encode and process information in two-
dimensional units called qubits. Using d-dimensional qudits instead may offer intrinsic …

We report an experimental investigation of quantum correlations in a two-qutrit spin system
in a single nitrogen-vacancy center in diamond at room temperatures. Quantum …

Informationally complete (IC) positive operator-valued measures (POVMs) are generalized
quantum measurements that offer advantages over the standard computational basis …

Ternary quantum information processing in superconducting devices poses a promising
alternative to its more popular binary counterpart through larger, more connected …
