Universal Quantum Computing Using Electronuclear Wavefunctions of Rare-Earth Ions

Gabriel Aeppli

We propose a scheme for universal quantum computing based on Kramers rare-earth ions. Their nuclear spins in the presence of a Zeeman-split electronic crystal field ground state act as "passive" qubits that store quantum information. The "active" qubits ar ...

Scaling silicon-based quantum computing using CMOS technology

Edoardo Charbon

As quantum processors grow in complexity, attention is moving to the scaling prospects of the entire quantum computing system, including the classical support hardware. Recent results in high-fidelity control of individual spins in silicon, combined with d ...

Dynamical Localization Simulated on Actual Quantum Hardware

Su Yeon Chang

Quantum computers are invaluable tools to explore the properties of complex quantum systems. We show that dynamical localization of the quantum sawtooth map, a highly sensitive quantum coherent phenomenon, can be simulated on actual, small-scale quantum pr ...

Quantum conformance test

Elena Losero, Marco Genovese

We introduce a protocol addressing the conformance test problem, which consists in determining whether a process under test conforms to a reference one. We consider a process to be characterized by the set of end products it produces, which is generated ac ...

Classical variational simulation of the Quantum Approximate Optimization Algorithm

Giuseppe Carleo

A key open question in quantum computing is whether quantum algorithms can potentially offer a significant advantage over classical algorithms for tasks of practical interest. Understanding the limits of classical computing in simulating quantum systems is ...

Roadmap on quantum nanotechnologies

Pasquale Scarlino

Quantum phenomena are typically observable at length and time scales smaller than those of our everyday experience, often involving individual particles or excitations. The past few decades have seen a revolution in the ability to structure matter at the n ...

Towards Quantum 3D Imaging Devices

Edoardo Charbon, Claudio Bruschini, Paul Mos, Samuel Burri, Arin Can Ülkü, Michael Alan Wayne

We review the advancement of the research toward the design and implementation of quantum plenoptic cameras, radically novel 3D imaging devices that exploit both momentum–position entanglement and photon–number correlations to provide the typical refocusin ...

Realization of a $CQ_3$ Qubit: energy spectroscopy and coherence

Pasquale Scarlino

The energy landscape of a single electron in a triple quantum dot can be tuned such that the energy separation between ground and excited states becomes a flat function of the relevant gate voltages. These so-called sweet spots are beneficial for charge co ...

Designing a DDS-Based SoC for High-Fidelity Multi-Qubit Control

Edoardo Charbon, Fabio Sebastiano

The design of a large-scale quantum computer requires co-optimization of both the quantum bits (qubits) and their control electronics. This work presents the first systematic design of such a controller to simultaneously and accurately manipulate the state ...

Strongly correlated Fermions strongly coupled to light

Jean-Philippe Brantut, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi

Strong quantum correlations in matter are responsible for some of the most extraordinary properties of materials, from magnetism to high-temperature superconductivity, but their integration in quantum devices requires a strong, coherent coupling with photo ...
