-
Hilbert–Schmidt inradius of the multiqubit stabilizer polytope
Is every \(n\)-qubit state of purity at most \(1/(2^n-1/2)\) a convex mixture of stabilizer states?
Unsolved -
Distillation of every Wigner-negative depolarized Strange state
Can every Wigner-negative state in the depolarized qutrit Strange-state family be distilled arbitrarily accurately by catalyst-free stabilizer operations?
Unsolved -
Qutrit magic-distillation thresholds beyond the ternary Golay code
Does any finite qutrit stabilizer-code protocol distill depolarized Strange states above the ternary Golay code’s threshold?
Unsolved -
Optimal asymptotic distillation yield of dephased T states
What is the optimal catalyst-free asymptotic \(T\)-state yield of a dephased single-qubit \(T\) state?
Unsolved -
Optimal universal eight-copy concentration to a CCZ state
What is the optimal success probability for a fixed catalyst-free stabilizer protocol that converts eight copies of an arbitrary unknown pure qubit into an exact \(|CCZ\rangle\) state?
Unsolved -
Asymptotic growth of the stabilizer rank of T-state tensor powers
Does the exact stabilizer rank of the tensor powers of the single-qubit magic state \(|T\rangle\) grow polynomially in the number of copies, or is it not polynomially bounded?
Unsolved -
Universal purification with classically simulable operations
Can classically simulable operations purify an unknown depolarized pure state from any number of copies?
