- Cloaking a qubit in a cavity - Nature Communications
Here we introduce a simple approach to further engineer the light-matter interaction in a driven cavity by controllably decoupling a qubit from the cavity’s photon population, effectively
- Superconducting Cavity Qubit with Tens of Milliseconds Single-Photon . . .
In this work, we report a single-photon qubit encoded in a novel superconducting cavity with a coherence time of 34 ms, representing an order of magnitude improvement compared to previous demonstrations
- [2211. 05758] Cloaking a qubit in a cavity - arXiv. org
Here we introduce a simple approach to further engineer the light-matter interaction in a driven cavity by controllably decoupling a qubit from the cavity's photon population, effectively cloaking the qubit from the cavity
- Dispersive nonreciprocity between a qubit and a cavity
Here, we present an experimental study of a nonreciprocal dispersive-type interaction between a transmon qubit and a superconducting cavity, arising from a common coupling to dissipative intermediary modes with broken time reversal symmetry
- Quantum qubit-optical cavity node: Effects of the temperature and . . .
The qubit–cavity system is a promising framework for quantum technology, with potential uses in quantum communication, quantum computation, and quantum detection In this work, we investigate four qubit(s)-cavity systems, using the Dicke model
- A superconducting dual-rail cavity qubit with erasure-detected logical . . .
In this work, we demonstrate a projective logical measurement of a dual-rail cavity qubit with integrated erasure detection and measure the qubit idling errors We measure the logical state preparation and measurement errors at the 0 01% level and detect over 99% of the cavity decay events as erasures
- Cavity quantum electrodynamics - Wikipedia
Cavity Quantum Electrodynamics (cavity QED) is the study of the interaction between light confined in a reflective cavity and atoms or other particles, under conditions where the quantum nature of photons is significant
- A superconducting dual-rail cavity qubit with erasure-detected . . . - Nature
In this work, we demonstrate a projective logical measurement of a dual-rail cavity qubit with integrated erasure detection and measure the qubit idling errors We measure the logical state
- Recovering Quantum Coherence of a Cavity Qubit Coupled to a Noisy . . .
By tracking the noisy ancilla trajectory and using real-time feedback, we successfully recover the lost coherence of the cavity qubit, achieving a fivefold increase in its pure dephasing time Additionally, by detecting ancilla errors and converting them into erasures, we improve the pure dephasing time by more than an order of magnitude
- Cloaking a qubit in a cavity - PMC
We show how an appropriately tailored drive on the qubit can decouple the qubit state and the cavity’s photon population from one another, resulting in both systems interacting only through vacuum fluctuations of the cavity field This qubit cloaking mechanism can be exploited to prepare non-classical states of the cavity field
