A quantum hamiltonian simulation benchmark

npj Quantum Information, 2022
Hamiltonian simulation is one of the most important problems in quantum computation, and quantum singular value transformation (QSVT) is an efficient way to simulate a general class of Hamiltonians.

Experimental graybox quantum system identification and control

npj Quantum Information
Understanding and controlling engineered quantum systems is key to developing practical quantum technology. However, given the current technological limitations, such as fabrication imperfections and environmental noise, this is not always possible.

Impact of charge noise on electron exchange interactions in semiconductors

npj Quantum Information, 2022
The electron exchange interaction is a promising medium for the entanglement of single-spin qubits in semiconductors as it results in high-speed two-qubit gates.

Flow Ambiguity: A Path Towards Classically Driven Blind Quantum Computation [PDF]

, 2017
Blind quantum computation protocols allow a user to delegate a computation to a remote quantum computer in such a way that the privacy of their computation is preserved, even from the device implementing the computation.

Spontaneous parametric down conversion without poling for silicon carbide and lithium niobate photonics

Scientific Reports
State-of-the-art photon sources based on spontaneous parametric down-conversion (SPDC) currently rely on artificial structuring of the material nonlinearity to satisfy phase-matching conditions. This technique, known as periodic poling, is available only

Quantum Computation Toward Quantum Gravity [PDF]

General Relativity and Gravitation, 2001
The aim of this paper is to enlight the emerging relevance of Quantum Information Theory in the field of Quantum Gravity. As it was suggested by J. A. Wheeler, information theory must play a relevant role in understanding the foundations of Quantum Mechanics (the "It from bit" proposal).

Nonlocality activation in a photonic quantum network

Nature Communications
Bell nonlocality refers to correlations between two distant, entangled particles that challenge classical notions of local causality. Beyond its foundational significance, nonlocality is crucial for device-independent technologies like quantum key ...

Quantum Computation with Quantum Dots

, 1997
We propose a new implementation of a universal set of one- and two-qubit gates for quantum computation using the spin states of coupled single-electron quantum dots.
