Why scientists are so skeptical of the LK-99 room temperature ambient pressure superconductor NYU Quantum Technology Lab 2023-08-05 | LK-99 is a candidate for a room temperature ambient pressure superconductor proposed by several authors at Qcentre in Korea. Since the original papers arxiv.org/abs/2307.12008arxiv.org/abs/2307.12037appeared on the arxiv on July 22, 2023, scientists have been skeptical whether the claims are true. In this video we break down why scientists are skeptical and see whether there is hope that LK-99 really lives up to its promises. This is a fast changing topic and was filmed on August 4, 2023 so there may be new developments since.

The limits of AI and ChatGPT: the common sense problem NYU Quantum Technology Lab 2023-05-01 | I talk about how how the recent emergence of artificial intelligence modelslike ChatGPT and their limitations. This is partly a response to Yejin Choi's TED talkyoutube.com/watch?v=SvBR0OGT5VIand Yann LeCun's comments regarding whether large language models are able to capture basic common sense of the human experience. I explain my own understanding of the extent to which AI will replace human workers and argue that this is limited.I talk about whether this puts limits on the mind-body problem and whether AI can ever replicate humans perfectly. #ai #chatgpt #gpt4

Google quantum computers error correction breakthough breakdown NYU Quantum Technology Lab 2023-02-25 | We go through Google Quantum AI's recent Nature paper, "Suppressing quantum errors by scaling a surface code logical qubit"nature.com/articles/s41586-022-05434-1The Google team experimentally realizes a 5x5 and 3x3 surface code, one of the most powerful quantum error correcting codes. We first explain the basics of quantum error correction using the bit flip code as an example and introduce the key ideas of syndrome measurements and stabilizers. Then we describe the basic experiment on the sycamore chip that Google did, and walk through the experimental results.

L9 Mobile phones and microwaves: How Things Work 2022 NYU Quantum Technology Lab 2022-05-12 | Lecture by Tim Byrnes for the course How Things Works at NYU Shanghai. Course Description:Do you know how electricity is generated and transported? How instruments create music? Why the sky is blue and why there are rainbows? Where the term “cell phone” comes from? What makes refrigerator magnets stick? How clocks keep time? Why ice skating is possible? How your computer monitor and plasma screen TV produce their colors and pictures? All of the devices that define contemporary living are applications of basic scientific discoveries. The principles underlying these devices are fascinating as well as useful, and explain as well many of the natural features and phenomena of the world around us. This course familiarizes you with some basic principles of physics through their applications to selected devices such as CD and DVD players, radio and cell phones, the basic electronic components of computers, lasers and LEDs, and even nuclear weapons. In learning thebasic physics behind these modern inventions, you will develop a deeper understanding of how the physical world works and gain a new appreciation of everyday phenomena that are ordinarily taken for granted. The course is designed for non-science students with an interest in the natural world. The basic physical ideas needed to understand how things operate are presented using some mathematics, but none beyond elementary high school level algebra.#howthingswork #electricity #physics

How to make a quantum time capsule NYU Quantum Technology Lab 2022-02-13 | Igor Ermakov of Skoltech tells us about his recent work on Almost complete local revivals and Quantum Time Capsules. This is a work recently published here:journals.aps.org/pra/abstract/10.1103/PhysRevA.104.L050202The method allows you to create a revival of the expectation value of a qubit inside virtually any type of many-body quantum Hamiltonian at a desired time, but engineering a suitable state. This allows you to mask the information in a state only until a particular revival time, that is freely choosable. #timecapsule #quantuminformation #quantum

The puzzling tension between faster-than-light communication and quantum mechanics NYU Quantum Technology Lab 2022-01-16 | We look at a paper by Nicolas Gisinarxiv.org/abs/1407.8122which considers a variation of the superluminal (faster-than-light) communication setup where quantum measurements are made of an entangled pair of qubits. In this paper, an ensemble of qubits is considered, so that a macroscopically large signal is obtained on Bob's side. This reformulates a famous tension that exists between relativity and quantum mechanics, where it is consistent, but for entirely different reasons.

Quantum entanglement between a tardigrade and a superconducting qubit: Schrodingers cat or hype? NYU Quantum Technology Lab 2021-12-23 | We take a look at a recent arxiv paper claiming entanglement between a tardigrade and a superconducting qubit. If this is true then this would be the first multicellular organism that is shown to be entangled, much like Schrodinger's famous thought experiment. But it has been criticized by many scientists for overclaiming. So is it really the breakthrough that is claimed?The paper:arxiv.org/abs/2112.07978
E2 Making a quantum computer from scratch: Polarization spectroscopy NYU Quantum Technology Lab 2021-12-19 | We talk about our efforts towards making a quantum computer based on cold neutral atom on atom chips. In this video we talk about polarization spectroscopy, a related technique to saturated absorption spectroscopy to frequency lock the laser and reduce its linewidth. We use a rubidium (Rb87) gas cell as atomic reference, and show the laser locking in action. The basic idea of the quantum computing scheme is here if you want to learn more about it. nyu.timbyrnes.net/research/quantum-information-using-bose-einstein-condensates
