On our radar

What we are watching.

These are papers the system has noticed but not yet written about. Each carries a short note on why it is being held: a result to confirm, a method to read in full, a claim worth a second pass before a briefing goes out.

Watchlist entries

arXiv quant-ph Error correction

Below-threshold logical error rates on a distance-7 surface code

Why we are watching The claimed error suppression sits close to the fault-tolerance threshold, so we want to read the calibration appendix before reporting the figure.

Quantum Journal Algorithms

A shallower circuit for the quantum linear-systems problem

Why we are watching The depth reduction depends on a sparsity assumption that may not hold for the cases readers care about, so we are checking how general the result is.

arXiv quant-ph Sensing

Entanglement-enhanced magnetometry past the standard quantum limit

Why we are watching The sensitivity gain is reported under ideal coherence times, and we want to see how it holds once realistic noise is added.

PRX Quantum Materials

Long-lived spin coherence in a silicon-carbide defect at room temperature

Why we are watching A room-temperature coherence time of this length would matter for practical devices, so we are waiting on an independent measurement before writing it up.

Quantum Journal Foundations

A tighter bound on contextuality as a resource for computation

Why we are watching The proof reframes an older argument, and we want to read it against the prior work it cites before deciding what is new here.
