... In the above example, the particle was able to penetrate into the classically disallowed region, though not very effectively, since the wavefunction decayed away exponentially the further you went into that region. But what if the classicaly forbidden region has only finite thickness? ...

The Power of Quantum Advice
... Karp-Lipton 1982: If NP P/poly, then coNPNP = NPNP. Our quantum analogue: If NP BQP/qpoly, then coNPNP QMAPromiseQMA. Idea: Let M be a YQP/poly machine that solves 3SAT. In QMA, guess the classical advice z to M, and check that some quantum witness | is consistent with z. Then, in PromiseQMA ...

... Before the advent of the formal development of quantum mechanics, a few simple, fundamental problems were worked out exactly. It was the case of the Bohr atomic model for the hydrogen atom. This kind of problem is treated in quantum mechanics and modern physics textbooks prior to the introduction of ...

“Measuring” the Density Matrix
... Schrödingers quantum mechanics and its statistical postulates are usually formulated in terms of a state (wave) function, ∣Ψ⟩ which is a solution to Schrödingers equation. Alternatively, these statistical postulates can be formulated in terms of a density operator ρop , which is defined as ρop = ∣ ...

... Fermions undergoing BCS type pairing interaction can be treated as hard-core bosons in real or momentum space depending on whether they interact strongly or weakly. In both cases, lattice points (or energy levels) are occupied by pairs or else they are empty. Therefore, the system can be described b ...

The Learnability of Quantum States

Call a configuration S=(s1,…,sm) good if every si is 0 or 1 (i.e., there are no collisions between bosons), and bad otherwise We assumed for simplicity that all configurations were good But suppose bad configurations dominated. Then M could be wrong on all good configurations, yet still “work” Furth ...
