Microsoft has created a quantum computing chip, Majorana 1, that relies on what it says is a “new state of matter” — one that exists beyond the primary liquid, solid, gas states that have underpinned science since Ancient Greece. Research into this fourth physical existence, called a “topological state,” earned three theoretical physicists the Nobel Prize in Physics in October. Unlike solids, liquids or gases, a topological state is not defined locally by how its particles are arranged, but by how their quantum wavefunction behaves — wrapping around itself globally, across the entire material.

Microsoft’s cloud computing platform will soon offer select customers access to quantum computers. More specifically, the three prototype quantum computers are from Honeywell and two startups, IonQ (spun out from the University of Maryland) and QCI (spun out of Yale University). Quantum computing isn’t ready for any real work, but Microsoft, like its rivals IBM and Google, wants to stake out a presence in the nascent field. Microsoft Quantum general manager Krysta Svore noted, “we need a global community.” Continue reading Microsoft Plans to Launch Quantum Computing in the Cloud
