Why the Quantitative Condition Fails to Reveal Quantum Adiabaticity
Abstract: After the two beautiful talks given by Giulio and Alioscia, who respectively introduced to us the very board worlds of non-local quantum games and quantum irreversibility, I would like to l...

Quantum Journal Club: Efficient Experimental Estimation of Fidelity of Linear Op
Abstract: We propose an efficiently measurable lower bound on quantum process fidelity of N-qubit controlled-Z gates. This bound is determined by average output state fidelities for N partially conju...

Quantum Journal Club: The Uncertainty Principle Determines the Nonlocality of Qu
Abstract: Two central concepts of quantum mechanics are Heisenberg’s uncertainty principle and a subtle form of nonlocality that Einstein famously called “spooky action at a distance.” These two f...

Quantum Simpsons Paradox and High Order Bell-Tsirelson Inequalities
Abstract: The well-known Simpson's Paradox, or Yule-Simpson Effect, in statistics is often illustrated by the following thought experiment: A drug may be found in a trial to increase the survival rat...

Source attack of decoy-state quantum key distribution using phase information
Abstract: I would like to talk about one of my recent works on quantum hacking, which is performed at USTC. We use linear optics to implement a USD attack on a decoy-state QKD system without phase ra...

Parallelization and factorization in quantum metrology
Abstract: The discussion will be about the quantum metrology in quantum networks. Prof. Giulio Chiribella will start the discussion with a presentation entitled "Parallelization and factorization in ...
