The truth about New Microsoft Majorana Chip
AI Summary
Summary of the Video Transcript
- Microsoft released a new Quantum chip called Majorana, featuring a new state of matter called Topological State.
- The chip uses topological qubits, which are more stable and less prone to errors due to environmental noise.
- Topological qubits are made from a new material called topoconductor, a combination of superconductor aluminum and semiconductor indium arsenide.
- The qubits require cooling to near absolute zero and tuning with magnetic fields.
- The quantum information is stored nonlocally in the system, making it more resilient to noise.
- Microsoft’s topological qubits promise to be 100 to 1000 times better in terms of noise rate.
- The Majorana chip currently features 8 qubits and is a proof of concept for the use and control of topological qubits.
- Google’s Willow chip, based on superconducting qubits, solved a 30-year-old problem in Quantum Computing error correction.
- Willow demonstrated that increasing the number of qubits can exponentially decrease errors.
- Intel is working on Quantum Dot technology, which is highly scalable due to the small size of the qubits (15nm) and compatibility with standard CMOS technology.
- Intel has produced a 300mm wafer full of Quantum Dot qubits, encoding quantum information in the spin of a single electron.
- Google and IBM are currently leading in the Quantum Computing race, but Microsoft’s approach at the device level with the Majorana chip is a significant innovation.
