Multimode microwave circuit optomechanics as a platform to study coupled quantum harmonic oscillators

Nathan Rafaël Bernier

Harmonic oscillators might be one of the most fundamental entities described by physics. Yet they stay relevant in recent research. The topological properties associated with exceptional points that can occur when two modes interact have generated much int ...

Mutually Coupled Time-to-Digital Converters (TDCs) for Direct Time-of-Flight (dTOF) Image Sensors

Edoardo Charbon, Preethi Padmanabhan, Augusto Ronchini Ximenes

Direct time-of-flight (dTOF) image sensors require accurate and robust timing references for precise depth calculation. On-chip timing references are well-known and understood, but for imaging systems where several thousands of pixels require seamless refe ...

4x40 Gb/s 2 pJ/bit Optical RX with 8ns Power-on and CDR-Lock Time in 14nm CMOS

Alessandro Cevrero, Ilter Ozkaya, Thomas Toifl

We report a low-power 4-channel NRZ optical RX including a digital burst-mode CDR measured up to 40Gb/s/lane in 14nm CMOS. The RX, designed for 850nm VCSEL based optical links, can wake-up and achieve phase-lock in 8ns at BER

Evidence for structural damping in a high-stress silicon nitride nanobeam and its implications for quantum optomechanics

Tobias Kippenberg, Dalziel Joseph Wilson, Sergey Fedorov, Ryan Daniel Schilling, Vivishek Sudhir, Hendrik Schütz

We resolve the thermal motion of a high-stress silicon nitride nanobeam at frequencies far below its fundamental flexural resonance (3.4 MHz) using cavity-enhanced optical interferometry. Over two decades, the displacement spectrum is well-modeled by that ...

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 ...

Phonon-Driven Selective Modulation of Exciton Oscillator Strengths in Anatase TiO2Nanoparticles

Majed Chergui, Edoardo Baldini, Tania Palmieri, Enrico Pomarico, Thomas Charles Henry Rossi, Malte Oppermann, Gerald Auböck

The way nuclear motion affects electronic responses has become a very hot topic in materials science. Coherent acoustic phonons can dynamically modify optical, magnetic, and mechanical properties at ultrasonic frequencies, with promising applications as se ...

Neural correlates of performance monitoring during discrete and continuous tasks

Michael Eric Anthony Pereira

Monitoring our actions is a key function of the brain for adaptive and successful behavior. Actions can be discrete such as when pressing a button, or continuous, such as driving a car. Moreover, we evaluate our actions as correct or erroneous (performance ...

Entrainment of Voluntary Movement to Undetected Auditory Regularities

Olaf Blanke, Leila Cammoun, Aaron Schurger, Nathan Quentin Faivre

In physics “entrainment” refers to the synchronization of two coupled oscillators with similar fundamental frequencies. In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked ...

Single-chip electron spin resonance detectors operating at 50 GHz, 92 GHz, and 146 GHz

Jürgen Brugger, Henrik Moodysson Rønnow, Giovanni Boero, Ivica Zivkovic, Alessandro Valentino Matheoud, Jens Anders, Gabriele Gualco

We report on the design and characterization of single-chip electron spin resonance (ESR) detectors operating at 50 GHz, 92 GHz, and 146 GHz. The core of the single-chip ESR detectors is an integrated LC-oscillator, formed by a single turn aluminum planar ...

Pixel parallel localized driver design for a 128 x 256 pixel array 3D 1Gfps image sensor

Edoardo Charbon, Takeharu Etoh

In this paper, a 3D 1Gfps BSI image sensor is proposed, where 128 × 256 pixels are located in the top-tier chip and a 32 × 32 localized driver array in the bottom-tier chip. Pixels are designed with Multiple Collection Gates (MCG), which collects photons s ...
