Physicists have not proved that we don’t live in the Matrix. Anyway, this is all somewhat far from my expertise, but insofar as I understand the paper, it looks like a serious contribution to our understanding

[과학] 양자역학과 고전역학의 시각 차이 // Poisson bracket and Ehrenfest theorem

[과학] 양자역학과 고전역학의 시각 차이 // Poisson bracket and Ehrenfest theorem

흔히 고전역학을 배우고 양자역학을 바로 배우는 학생들 중에서 몇가지 쉽게 착각하는 것이 있다. 이번 포스팅에는 그 중 하나를 이야기 해 보려고 한다. 바로 commutator 와 poisson bracket 이야기이다. 먼저 각각에 정의를 알아보자 commutator 는 만약 A,B 가 실수라면 commutator 는 자연스럽게 사라지고 무의미해진다. 양자역학에서는

China Demonstrates World’s First Quantum-Encrypted Video Call

China Demonstrates World’s First Quantum-Encrypted Video Call

In this demonstration, a secure key was generated from a quantum satellite called Micius that launched in August 2016. This satellite creates photons suspended in superposition. The peculiar properties

Getting Mind Blown for Breakfast

Here's a good old conversation about quantum mechanics recently in Joe Rogan's Experience #1003. The full video is recommended too. Sean Carroll is one of my favourite science communicators, and I remember

우리는 살면서 자주 "양자역학" 이라는 단어를 들어왔다. 굳이 "양자역학" 이라는 단어를 안 들어봤어도, "미시세계" "확률론적 세계" 등은 살면서 몇번이곤 들어 봤을 것이다. 양자역학은 TV 브라운 관부터 시작해서 전자레인지의 작동원리, 레이저의 원리, 컴퓨터 메모리칩, 반도체, 원자력

What is Consciousness? What is Its Purpose?

I wanted to share with everyone this awesome 1 hour documentary. Some of the insights are truly life changing, as throughout the docu it really makes you question a lot of cultural indoctrinations and

Modern Physics > Quantum Mechanics > The uncertainty principle

Modern Physics > Quantum Mechanics > The uncertainty principle

Young's experience for electrons, in particular the formation of an interference pattern even when the electron beam is so thin that there is no doubt that electrons arrive one by one on the screen shows
