Quantum Magic in High Energy Collision
Ying-Ying Li, Ian Low, Yi-Lin Wang +1
Quantum magic, or nonstabilizerness, is a quantum resource associated with computational advantage in quantum systems. In high energy collisions, Quantum Electrodynamics (QED) is i…
A Quantum Computational Determination of the Weak Mixing Angle in the Standard Model
Qiaofeng Liu, Ian Low, Zhewei Yin
The weak mixing angle is a fundamental constant in the Standard Model (SM) and measured at the boson mass to be in the $\over…
Quantum Magic in Quantum Electrodynamics
Qiaofeng Liu, Ian Low, Zhewei Yin
In quantum computing, non-stabilizerness -- the magic -- refers to the computational advantage of certain quantum states over classical computers and is an essential ingredient for…
Maximal Magic for Two-qubit States
Qiaofeng Liu, Ian Low, Zhewei Yin
Magic is a quantum resource essential for universal quantum computation and represents the deviation of quantum states from those that can be simulated efficiently using classical…
Entanglement Entropy is Elastic Cross Section
Ian Low, Zhewei Yin
We present universal relations between entanglement entropy, which quantifies the quantum correlation between subsystems, and the elastic cross section, which is the primary observ…
An Area Law for Entanglement Entropy in Particle Scattering
Ian Low, Zhewei Yin
The scattering cross section is the effective area of collision when two particles collide. Quantum mechanically, it is a measure of the probability for a specific process to take…
