Quantum state manipulation of single atom magnets using the hyperfine interaction

Harald Brune, François Patthey, Donat Fabian Natterer, Edgar Fernandes, Dante Philippe Sblendorio

The magnetic quantum states of holmium single atom magnets on MgO(100) have proven extremely robust when exposed to high magnetic fields and temperatures up to 35 K. Here we address the stability of Ho at small magnetic fields, where the hyperfine interact ...

Polar Codes for Arbitrary Classical-Quantum Channels and Arbitrary cq-MACs

We prove polarization theorems for arbitrary classical-quantum (cq) channels. The input alphabet is endowed with an arbitrary Abelian group operation, and an Anion-style transformation is applied using this operation. It is shown that as the number of pola ...

Dissipation as a resource in circuit quantum electromechanics

László Dániel Tóth

A primary challenge in quantum science and technology is to isolate the fragile quantum states from their environment in order to prevent the irreversible leakage of energy and information which causes decoherence. In the late 1990s, however, a new paradig ...

Cryo-CMOS for quantum computing

Edoardo Charbon

Cryogenic CMOS, or cryo-CMOS circuits and systems, are emerging in VLSI design for many applications, in primis quantum computing. Fault-tolerant quantum bits (qubits) in surface code configurations, one of the most accepted implementations in quantum comp ...

An Adaptive Sublinear-Time Block Sparse Fourier Transform

Volkan Cevher, Jonathan Mark Scarlett, Mikhail Kapralov, Amir Zandieh

The problem of approximately computing the

Heralded Single-Phonon Preparation, Storage, and Readout in Cavity Optomechanics

Tobias Kippenberg, Christophe Marcel Georges Galland, Nicolas Piro Mastracchio

We show how to use the radiation pressure optomechanical coupling between a mechanical oscillator and an optical cavity field to generate in a heralded way a single quantum of mechanical motion (a Fock state). Starting with the oscillator close to its grou ...

Cavity Quantum Optomechanics: Coupling Light And Micromechanical Oscillators

Tobias Kippenberg, Albert Schliesser, Stefan Alexander Weis

Cavity optomechanics(1) is a new research field that has seen spectacular advances in recent years. Optomechanics combines advances in nano-and electromechanical systems with radiation pressure enabled control. The radiation pressure backaction enables to ...

Learning non-parametric basis independent models from point queries via low-rank methods

Volkan Cevher, Hemant Tyagi

We consider the problem of learning multi-ridge functions of the form f (x) = g(Ax) from point evaluations of f. We assume that the function f is defined on an l(2)-ball in R-d, g is twice continuously differentiable almost everywhere, and A is an element ...

Quantum-Coherent Coupling of a Mechanical Oscillator to an Optical Cavity Mode

Tobias Kippenberg, Albert Schliesser, Stefan Alexander Weis

We demonstrate an optomechanical microresonator in which optical and mechanical degrees of freedom exchange energy at a rate exceeding the relevant decoherence rates in the system, enabling quantum control of a mechanical oscillator with light. ...
