01
Logical qubits still Markovian?
Physical noise forgets; syndrome memory can break logical GST / RB.
APS 2026
02
Can we untangle crosstalk?
Separate SPAM, gate error, and neighbor coupling—no independence assumed.
Simultaneous GST
03
What noise stays unlearnable?
Mid-circuit measurements unlock Pauli parameters cycle benchmarking can't see.
MCM cycle BB
04
Few shots, real certificates?
Classical shadows turn random measurements into scalable checks.
IWQCVV
05
Is one number enough?
A single fidelity doesn't predict useful quantum advantage.

Can one prover certify BQP?
Information-theoretic single-prover QPIP is still open.

Must certification entangle copies?
Optimal rates with limited t-copy measurements remain open.

Crosstalk—or just memory?
Non-Markovianity can fake crosstalk in GST fits.

Does crosstalk go logical?
Low-weight coupling can become logical ZZ in multi-logical blocks.
