Quantum minimal surfaces from quantum error correction
SciPost Physics, 2022 We show that complementary state-specific reconstruction of logical (bulk) operators is equivalent to the existence of a quantum minimal surface prescription for physical (boundary) entropies.

Implementation of the Five Qubit Error Correction Benchmark [PDF]
, 2001 The smallest quantum code that can correct all one-qubit errors is based on five qubits. We experimentally implemented the encoding, decoding and error-correction quantum networks using nuclear magnetic resonance on a five spin subsystem of labeled ...

Quantum error correction may delay, but also cause, entanglement sudden death
, 2008 Dissipation may cause two initially entangled qubits to evolve into a separable state in a finite time. This behavior is called entanglement sudden death (ESD). We study to what extent quantum error correction can combat ESD.

Recovery in quantum error correction for general noise without measurement [PDF]
, 2010 It is known that one can do quantum error correction without syndrome measurement, which is often done in operator quantum error correction (OQEC). However, the physical realization could be challenging, especially when the recovery process involves high-

Effectiveness of the syndrome extraction circuit with flag qubits on IBM quantum hardware [PDF]
QuantumLarge-scale quantum circuits are required to exploit the advantages of quantum computers. Despite significant advancements in quantum hardware, scalability remains a challenge, with errors accumulating as more qubits and gates are added. To overcome this

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Autonomous error correction of a single logical qubit using two transmons
Nature CommunicationsLarge-scale quantum computers will inevitably need quantum error correction to protect information against decoherence. Traditional error correction typically requires many qubits, along with high-efficiency error syndrome measurement and real-time ...

Generalization of Quantum Error Correction via the Heisenberg Picture
, 2007 We show that the theory of operator quantum error correction can be naturally generalized by allowing constraints not only on states but also on observables.
