How Are Quantum Eigenfunctions of Hydrogen Atom Related To Its Classical Elliptic Orbits?
Yixuan Yin, Tiantian Wang, Biao Wu
We show that a highly-excited energy eigenfunction of hydrogen atom can be approximated as an equal-weight superposition of classical elliptic orbits with energy…
Quantum Computing by Cooling
Jiajin Feng, Biao Wu, Frank Wilczek
Interesting problems in quantum computation take the form of finding low-energy states of (pseudo)spin systems with engineered Hamiltonians that encode the problem data. Motivated…
Classical Computer, Quantum Computer, and the Gödel's theorem
Biao Wu
I show that the cloneability of information is the key difference between classical computer and quantum computer. As information stored and processed by neurons is cloneable, brai…
Microscope for Quantum Dynamics with Planck Cell Resolution
Zhenduo Wang, Jiajin Feng, Biao Wu
We introduce the out-of-time-correlation(OTOC) with the Planck cell resolution. The dependence of this OTOC on the initial state makes it function like a microscope, allowing us to…
Genuine Quantum Chaos and Physical Distance Between Quantum States
Zhenduo Wang, Yijie Wang, Biao Wu
We show that there is genuine quantum chaos despite that quantum dynamics is linear. This is revealed by introducing a physical distance between two quantum states. Qualitatively d…
Everett's Theory of the Universal Wave Function
Biao Wu
This is a tutorial for the many-worlds theory by Everett, which includes some of my personal views. It has two main parts.The first main part shows the emergence of many worlds in…
