The quantum Zeno effect asserts that quantum measurements inhibit simultaneous unitary
dynamics when the “collapse” events are sufficiently strong and frequent. This applies in the …

Cat qubits, for which logical| 0⟩ and| 1⟩ are coherent states|±α⟩ of a harmonic mode, offer
a promising route towards quantum error correction. Using dissipation to our advantage so …

Efficient suppression of errors without full error correction is crucial for applications with
noisy intermediate-scale quantum devices. Error mitigation allows us to suppress errors in …

Delay lines that store quantum information are crucial for advancing quantum repeaters and
hardware efficient quantum computers. Traditionally, they are realized as extended systems …

Quantum metrology, a cornerstone of quantum technologies, exploits entanglement and
superposition to achieve higher precision than classical protocols in parameter estimation …

Understanding the mechanisms of qubit decoherence is a crucial prerequisite for improving
the qubit performance. In this paper, we discuss the effects of residual Bogolyubov …

Quantum low-density parity-check (qLDPC) codes are a promising construction for
drastically reducing the overhead of fault-tolerant quantum computing (FTQC) architectures …

We study double quantum dots coupled to a quasistatic cavity mode with high mode-volume
compression allowing for strong light-matter coupling. Besides the cavity-mediated …

В томе 2 книги основное внимание сосредоточено на разъяснении (по возможности
подробном) особенностей логических «парадоксов» квантовой механики (как …

We propose a scheme for realizing parity measurement of cat-state qubits based on a
topological quantum phase transition. The cat-state qubits, formed by the bosonic modes in …
