Ground state preparation and energy estimation on early fault-tolerant quantum computers via quantum eigenvalue transformation of unitary matrices [PDF]
PRX Quantum, 2022 Under suitable assumptions, the algorithms in [Lin, Tong, Quantum 2020] can estimate the ground state energy and prepare the ground state of a quantum Hamiltonian with near-optimal query complexities.

Emergent quantum state designs and biunitarity in dual-unitary circuit dynamics [PDF]
Quantum, 2022 Recent works have investigated the emergence of a new kind of random matrix behaviour in unitary dynamics following a quantum quench. Starting from a time-evolved state, an ensemble of pure states supported on a small subsystem can be generated by ...

Asymptotically Optimal Circuit Depth for Quantum State Preparation and General Unitary Synthesis [PDF]
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2021 The quantum state preparation problem aims to prepare an $n$ -qubit quantum state $|\psi _{v}\rangle =\sum _{k=0}^{2^{n}-1}v_{k}|k\rangle $ from the initial state $|0\rangle ^{\otimes n}$ , for a given unit vector $v=(v_{0},v_{1},v_{2},\ldots,v_{2 ...

THE ROLE OF PARADIPLOMACY AND THE POTENTIAL PROTO-DIPLOMACY IN THE UNITARY STATE
Journal of Islamic World and Politics, 2022 This article aims to explain the study of paradiplomacy in the unitary state. With the case study of Indonesia, the author explains the role of paradiplomacy and the potential of proto-diplomacy in a unitary state like Indonesia.

Unitary Complexity and the Uhlmann Transformation Problem [PDF]
arXiv.org, 2023 State transformation problems such as compressing quantum information or breaking quantum commitments are fundamental quantum tasks. However, their computational difficulty cannot easily be characterized using traditional complexity theory, which focuses

A One-Query Lower Bound for Unitary Synthesis and Breaking Quantum Cryptography [PDF]
IACR Cryptology ePrint Archive, 2023 The Unitary Synthesis Problem (Aaronson-Kuperberg 2007) asks whether any n-qubit unitary U can be implemented by an efficient quantum algorithm A augmented with an oracle that computes an arbitrary Boolean function f.
