Error Correction of Beamsplitter-Generated Entangled GKP States
Moritz Fontboté-Schmidt, Jeremy Metzner, Florence Berterottière +8
To be useful, quantum computers will be required to successfully correct errors occurring at the hardware level. Bosonic codes provide a hardware-efficient option for error correct…
Non-linear cooling and control of a mechanical quantum harmonic oscillator
Matteo Simoni, Ivan Rojkov, Matteo Mazzanti +7
Non-linearities are a key feature allowing non-classical control of quantum harmonic oscillators. However, when non-linearities are strong, designing protocols for control is often…
A 3-dimensional scanning trapped-ion probe
Tobias Sägesser, Shreyans Jain, Pavel Hrmo +6
Single-atom quantum sensors offer high spatial resolution and high sensitivity to electric and magnetic fields. Among them, trapped ions offer exceptional performance in sensing el…
Modular variable laser cooling for efficient entropy extraction
Brennan de Neeve, Thanh-Long Nguyen, Alexander Ferk +5
We propose and experimentally demonstrate a method for laser cooling an oscillator based on sequences of spin-state-dependent displacements followed by spin repumping. For a therma…
