In the past two decades, the density matrix renormalization group (DMRG) has emerged as
an innovative new method in quantum chemistry relying on a theoretical framework very …

This is a partly non-technical introduction to selected topics on tensor network methods,
based on several lectures and introductory seminars given on the subject. It should be a …

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

The ground state of the spin-1 Affleck, Kennedy, Lieb, and Tasaki (AKLT) model is a
paradigmatic example of both a matrix product state and a symmetry-protected topological …

The matrix product state (MPS) belongs to the most important models in, for example,
quantum information sciences and condensed-matter physics. However, realizing an N …

Blind quantum computation is a new secure quantum computing protocol which enables
Alice (who does not have sufficient quantum technology) to delegate her quantum …

Ground states of spin lattices can serve as a resource for measurement-based quantum
computation. Ideally, the ability to perform quantum gates via measurements on such states …

Verification is a task to check whether a given quantum state is close to an ideal state or not.
In this paper, we show that a variety of many-qubit quantum states can be verified with only …

We present an architecture for encoding two qubits within the optical “clock” transition and
nuclear spin-1/2 degree of freedom of neutral ytterbium-171 atoms. Inspired by recent high …

We present a new framework for assessing the power of measurement-based quantum
computation (MBQC) on short-range entangled symmetric resource states, in spatial …
