Decoding quantum color codes with MaxSAT [PDF]

Quantum
In classical computing, error-correcting codes are well established and are ubiquitous both in theory and practical applications. For quantum computing, error-correction is essential as well, but harder to realize, coming along with substantial resource ...

Measurement-induced phase transitions in sparse nonlocal scramblers

Physical Review Research, 2022
Measurement-induced phase transitions arise due to a competition between the scrambling of quantum information in a many-body system and local measurements.

Extending Construction X for Quantum Error-Correcting Codes [PDF]

, 2013
In this paper we extend the work of Lisonek and Singh on construction X for quantum error-correcting codes to finite fields of order $p^2^ where p is prime.

Multi-Error-Correcting Amplitude Damping Codes

, 2010
We construct new families of multi-error-correcting quantum codes for the amplitude damping channel. Our key observation is that, with proper encoding, two uses of the amplitude damping channel simulate a quantum erasure channel.

Unitary Application of the Quantum Error Correction Codes [PDF]

Communications in Theoretical Physics, 2012
Summary: For applying the perfect code to transmit quantum information over a noise channel, the standard protocol contains four steps: the encoding, the noise channel, the error-correction operation, and the decoding. In present work, we show that this protocol can be simplified.

Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

Advanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Contextuality of Quantum Error-Correcting Codes

PRX Quantum
Fault-tolerant quantum computation requires quantum error correction (QEC), which relies on entanglement to protect information from local noise. Achieving universality, however, demands overcoming the Eastin-Knill theorem.

Error-correcting codes for fermionic quantum simulation

SciPost Physics
Utilizing the framework of $\mathbb{Z}_2$ lattice gauge theories in the context of Pauli stabilizer codes, we present methodologies for simulating fermions via qubit systems on a two-dimensional square lattice. We investigate the symplectic automorphisms

Approximate Quantum Error-Correcting Codes and Secret Sharing Schemes

, 2005
It is a standard result in the theory of quantum error-correcting codes that no code of length n can fix more than n/4 arbitrary errors, regardless of the dimension of the coding and encoded Hilbert spaces. However, this bound only applies to codes which
