A universal quantum rewinding protocol with an arbitrarily high probability of success

David Trillo, Benjamin Dive, Miguel Navascués

We present a universal mechanism that, acting on any target qubit, propagates it to the state it had T time units before the experiment started. This protocol works by setting the…

Demonstration of universal time-reversal for quantum processes

Peter Schiansky, Teodor Strömberg, David Trillo +4

Although the laws of classical physics are deterministic, thermodynamics gives rise to an arrow of time through irreversible processes. In quantum mechanics the unitary nature of t…

Contextuality in infinite one-dimensional translation-invariant local Hamiltonians: strengths and limits

Kaiyan Yang, Xiao Zeng, Yujing Luo +4

In recent years there has been a growing interest in treating many-body systems as Bell scenarios, where lattice sites play the role of distant parties and only near-neighbor stati…

Testing real quantum theory in an optical quantum network

Zheng-Da Li, Ya-Li Mao, Mirjam Weilenmann +12

Quantum theory is commonly formulated in complex Hilbert spaces. However, the question of whether complex numbers need to be given a fundamental role in the theory has been debated…

Optimized detection of high-dimensional entanglement

Xiao-Min Hu, Wen-Bo Xing, Yu Guo +9

Entanglement detection is one of the most conventional tasks in quantum information processing. While most experimental demonstrations of high-dimensional entanglement rely on fide…

A purification postulate for quantum mechanics with indefinite causal order

Mateus Araújo, Adrien Feix, Miguel Navascués +1

To study which are the most general causal structures which are compatible with local quantum mechanics, Oreshkov et al. introduced the notion of a process: a resource shared betwe…
