• Abstract: We describe a protocol for perfectly transferring a quantum state from one party to another under the dynamics of a fixed, engineered Hamiltonian. Our protocol combines the concepts of fractional revival, dual rail encoding, and a rare glimpse of the anti-Zeno effect. Remarkably, the transfer happens faster than the speed limit for perfect quantum state transfer [1, 2].

• Dissipation-accelerated entanglement generation [0.2356141385409842]
  We propose a scheme for speeding up the generation of quantum entanglement between two coupled qubits by introducing a strong dissipation channel to one of these qubits. The time needed to conditionally attain the maximal entanglement is monotonously decreased as the dissipative rate is increased. This scheme can be generalized to accelerate the production of the W state for the three-qubit system.
