Intro to Quantum Computing - Michele Mosca - USEQIP 2011

I woke up at 4am and this was on my phon

[@lawaklawakpeace9333]

Bruh just did the same, man feels like deja vu

[@hboyO2]

Lmao same, I just fell asleep and found this when I woke up

[@eligraham55]

I'm looking forward to studying Quantum Computing, what a concept.

[@joseluisarmenta]

why the trace is not from a matrix he used a ket of x at 2:22

[@element4element4]

Do you mean 2:20:00? I'm that case, you are right. He was abusing the notation, he meant taking the trace of a density matrix which is equal to that vector (ket) times its dual (bra).

Whyvisbrhis 2 HOURS long..that's way too long. Don't people get bored watching this?

Intro to the Ultimate Quantum Computing - The biggest and the most powerful Computer System in the entire Universe- The Universe itself. Quantum Entanglement is not only at microscopic or subatomic scale but it is also true at macroscopic scale up to a cosmic scale. This is proven by the empirical Theory of Quantum Gravitation, Quantum Gravitational Entanglement and Gravitational Quantum Computation for the entire Universe. These are the TRINITY (3-in-1) Equations and Codes For QUANTUM GRAVITATION, QUANTUM GRAVITATIONAL ENTANGLEMENT and GRAVITATIONAL QUANTUM COMPUTATION - The HOLY GRAILS of Physics: 1. Quantum Anti-Gravity = Spin Up Quantum Entanglement = 0 Rhu Bit or R Bit: QAG = ∆QGOρ < ∆QGFρ = ↑α 2. Quantum Gravity = Spin Down Quantum Entanglement = 1 Rhu Bit or R Bit: QG = ∆QGOρ > ∆QGFρ = ↓α 3. Quantum Neutral Gravity = Superposition Quantum Entanglement = 01 or 10 Rhu Bit or R Bit: QNG = ∆QGOρ = ∆QGFρ = ↑↓α We now have a working Quantum Theory of Gravity that is testable and complete with reproducible empirical experiments with the same results if repeated over and over again and again, confirmed by empirical observations in nature with 7-Sigma level results, guided by empirical laws and physical/mathematical Trinity God Equations that are predictive, precise and does no collapse even in high energies of Big Bang and singularity of Black Hole. FYI: Quantum Gravity or Quantum Gravitation have three types that are equivalent to and manifested by Quantum Computational Gravitation- the biggest and most powerful Computer Software Program and Hardware in the Universe and Quantum Gravitational Entanglement - a Quantum Entanglement in Macroscopic Cosmic Scale namely: 1. Quantum Anti-Gravity = Spin Up Quantum Entanglement State; 2. Quantum Neutral Gravity = Superposition Quantum Entanglement State; and 3. Quantum Gravity = Spin Down Quantum Entanglement State. More detailed information could be found on the published papers 2 years ago in London, Paris, and Zurich, online and at the two scientific Journals ACADEMIA and REAL TRUE NATURE. Alternatively, you can google the name of the author ROEL REAL ROVIRA to arrive at the published paper on Quantum Gravity. Most recently, additional two well respected scientific journals namely NATURE and the AMERICAN PHYSICAL SOCIETY APS Physical Review Journals have officially invited this author to submit manuscripts on his Research on Quantum Gravity for publication for PRX QUANTUM in preparation for a celebration for International Year of Quantum IYQ 2025 to showcase the best papers of the year. Quantum Gravitation is governed by and follow the Trinity Laws, Mathematics and Physics of Quantum Gravitation, Gravitational Quantum Computation and Quantum Gravitational Entanglement. We now have a new Laws of Physics which are the heart of the Quantum Theory of Gravity published in London. Paris and Zurich last December 2022 as follows: 1. First Law of Quantum Gravitation: Rovira’s Universal Law of Quantum Gravitation: “The greater mass density of gravitating Quantum Objects than the Quantum Gravitational Field causes a downward acceleration of the Quantum Objects in a Quantum Gravitational Field instantaneously mediated by Graviton.” - Roel Real Rovira Equation for Quantum Gravity, and Spin Down Quantum Gravitational Entanglement: QG = ∆QGOρ > ∆QGFρ = ↓α Where: QG is Quantum Gravity in Rovira (value of downward acceleration force due to quantum gravity) in kg. ∆QGOρ is Differential Change in greater mass density of Quantum Gravitating Objects than the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↓α is the Resultant Downward Acceleration of Gravitating Quantum Objects in mtr/sec. 2. Second Law of Quantum Gravitation: Rovira’s Universal Law of Quantum Anti-Gravity. “The lesser mass density of gravitating Quantum Objects than the Quantum Gravitational Field causes an upward acceleration of the Quantum Objects in a Quantum Gravitational Field instantaneously mediated by Graviton.” -Roel Real Rovira Equation for Quantum Anti-Gravity/Spin Up Quantum Gravitational Entanglement: QAG = ∆QGOρ < ∆QGFρ = ↑α Where: QAG is Quantum Anti-Gravity in Rovira (value of upward acceleration force due to quantum anti-gravity) in kg. ∆QGOρ is Differential Change in lesser mass density of Quantum Anti-Gravitating Objects than the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↑α is the Resultant Upward Acceleration of Anti-Gravitating Quantum Objects in mtr/sec. 3. Third Law of Quantum Gravitation: Rovira’s Law of Quantum Neutral Gravitation. “The equal mass density of gravitating Quantum Objects and the Quantum Gravitational Field causes a zero acceleration or floating or hoovering of the gravitating Quantum Objects in a Quantum Gravitational Field, instantaneously mediated by Graviton.” - Roel real Rovira Equation for Quantum Neutral Gravity and Superposition Quantum Gravitational Entanglement: QNG = ∆QGOρ = ∆QGFρ = ↑↓α Where: QNG is Quantum Neutral Gravity in Rovira (value of zero acceleration force due to quantum neutral gravity) in kg. ∆QGOρ is Differential Change in equal mass density of Quantum Neutral Gravitating Objects to the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↑↓0α is the Resultant zero acceleration or non-acceleration of Neutral Gravitating Quantum Objects in mtr/sec. For more detailed information on these 3-in-1 Trinity Laws and Equations for Quantum Gravitation, Gravitational Quantum Computation, and Quantum Gravitational Entanglement - The Real True Nature of Quantum Gravitation, look it up at the two scientific journals ACADEMIA and REAL TRUE NATURE or google the name of the author ROEL REAL ROVIRA.

[@ukvaishnav]

Does anyone know the book he mentioned?

[@ever.silva7]

Quantum Computation and Quantum Information: A. Nielsen, Isaac L. Chuang is mentioned at 02:13:42

[@joseluisarmenta]

whats is T capital?

[@RolandIshaya]

As i am concerned the Quantumcomputer can be unstable (Superposition). Or do you use a benefit from the Quantum Superposition? Intels Roadmap will go to 5nm in 2020, its smaller and will have 100% functionality at one Transistor in one state.

[@elosant2061]

Hello from the future, Intel did not get to a 5nm process in 2020 lol.

[@RolandIshaya]

@@elosant2061 really? i go and take a look

[@RickBeacham]

I would say that different forms of computing will solve different problems taking advantage of each ones uniqueness.

[@arunvinodh]

Great Presentation. Thanks a lot professor.

[@RickBeacham]

I don't understand it either.. But what i do understand is this... George Boole's rules do not work with quantum computing so new ones must be found that take advantage of this fact. Or rather they can simulate a classical pc or any on a quantum computer.. Right? Plus the environment housing this quantum computer must be robust enough to work properly... How can probability work on a classical PC or biological PC 48% of the time?? :-(

[@BlessingMeshach]

Very well explained..

[@RickBeacham]

Why not build a quantum computer in outer space first taking advantage of the properties of space?

[@numerical25]

This video is 2 hours long, HAHAHAHAAHAHAHA, you have to have a really big passion for Quantum Computers to watch this. I am a programmer and I don't have the patients to sit through this. At least not without asking questions. Cause believe me I would to keep myself awake.
