Single-atom-based asynchronous photonic interconnect for scalable modular quantum computing
Jérémy Raskop, Nadav Kandel, Geva Arwas +6
Scaling quantum computation beyond the capacity of a single quantum processing unit requires quantum interconnects between modular processors. Optical photons are natural carriers…
Shot-to-shot noise cancellation for parametric oscillators
Martynas Skrabulis, Martin Colombano Sosa, Nicola Carlon Zambon +4
Powerful approaches to squeeze the motional state of a harmonic oscillator rely on the stepwise modulation of its resonance frequency. Such protocols can be limited by forces that…
Electro-optic conversion of itinerant Fock states
Thomas Werner, Erfan Riyazi, Samarth Hawaldar +10
Superconducting qubits are a leading candidate for utility-scale quantum computing due to their fast gate speeds and steadily decreasing error rates. The requirement for millikelvi…
Nanomechanical sensor resolving impulsive forces below its zero-point fluctuations
Martynas Skrabulis, Martin Colombano Sosa, Nicola Carlon Zambon +4
The sensitivity of a mechanical transducer is ultimately limited by its inherent quantum fluctuations. Here, we use an optically levitated nanoparticle to measure impulsive forces…
Motional entanglement of remote optically levitated nanoparticles
Nicola Carlon Zambon, Massimiliano Rossi, Martin Frimmer +4
We show how to entangle the motion of optically levitated nanoparticles in distant optical tweezers. The scheme consists in coupling the inelastically scattered light of each parti…
Quantum Delocalization of a Levitated Nanoparticle
Massimiliano Rossi, Andrei Militaru, Nicola Carlon Zambon +4
Every massive particle behaves like a wave, according to quantum physics. Yet, this characteristic wave nature has only been observed in double-slit experiments with microscopic sy…
Feedback cooling a levitated nanoparticle's libration to below 100 phonons
Jialiang Gao, Fons van der Laan, Joanna A. Zielinska +3
Macroscopic rotors are interesting model systems to test quantum theory and for quantum sensing. A promising approach for bringing these systems to the quantum regime is to combine…
State Expansion of a Levitated Nanoparticle in a Dark Harmonic Potential
Eric Bonvin, Louisiane Devaud, Massimiliano Rossi +7
Levitated nanoparticles in vacuum are prime candidates for generating macroscopic quantum superposition states of massive objects. Most protocols for preparing these states necessi…
Hybrid Paul-optical trap with large optical access for levitated optomechanics
Eric Bonvin, Louisiane Devaud, Massimiliano Rossi +7
We present a hybrid trapping platform that allows us to levitate a charged nanoparticle in high vacuum using either optical fields, radio-frequency fields, or a combination thereof…
Optomechanical sideband asymmetry explained by stochastic electrodynamics
Lukas Novotny, Martin Frimmer, Andrei Militaru +3
Within the framework of stochastic electrodynamics we derive the noise spectrum of a laser beam reflected from a suspended mirror. The electromagnetic field follows Maxwell's equat…
Suppressing Recoil Heating in Levitated Optomechanics using Squeezed Light
C. Gonzalez-Ballestero, J. A. Zielińska, M. Rossi +5
We theoretically show that laser recoil heating in free-space levitated optomechanics can be arbitrarily suppressed by shining squeezed light onto an optically trapped nanoparticle…
White-noise fluctuation theorem for Langevin dynamics
Max Innerbichler, Andrei Militaru, Martin Frimmer +2
Fluctuation theorems based on time-reversal have provided remarkable insight into the non-equilibrium statistics of thermodynamic quantities like heat, work, and entropy production…
Encoding information in the mutual coherence of spatially separated light beams
Alfonso Nardi, Shawn Divitt, Massimiliano Rossi +4
Coherence has been used as a resource for optical communications since its earliest days. It is widely used for multiplexing of data, but not for encoding of data. Here we introduc…
Ponderomotive squeezing of light by a levitated nanoparticle in free space
Andrei Militaru, Massimiliano Rossi, Felix Tebbenjohanns +3
A mechanically compliant element can be set into motion by the interaction with light. In turn, this light-driven motion can give rise to ponderomotive correlations in the electrom…
