Complex numbers are essential to achieve the most accurate quantum-mechanical description of nature, according to experiments done by two independent teams of physicists. While the mathematics of complex numbers underlies modern quantum theory, it is also possible to describe the quantum world purely in terms of real numbers.

As a member of the LISA and Einstein Telescope consortia, his research areas are gravitational waves, nonlocal quantum gravity, multifractal spacetimes, cosmologies beyond the standard model, and string theory. I mainly work on two theories of gravitation: multifractional spacetimes and nonlocal quantum gravity.

Since its inception, quantum theory has presented us with many strange and seemingly paradoxical phenomena. One of the oddest examples is the quantum Cheshire cat effect, in which properties of quantum objects become disembodied from the objects themselves. A new spin on the quantum Cheshire cat.

Subsequent studies have produced nothing definitive. BECs (ultracold gases of trapped atoms all cooled to the quantum ground state of the trap) of highly magnetic atoms can spontaneously form regular, ordered clusters in an applied magnetic field, showing the emergence of supersolidity from a completely isotropic superfluid state. “The

Quantum computers are often touted as the solution to all our problems. Fuelled by this enthusiasm, a number of quantum computing firms have started joining established markets. However, despite this interest, there is still a lot of uncertainty around the near-term uses of quantum computers. Optimization is hard.

These personal stories are interspersed with long scientific passages explaining Hawking’s work on the nature of black holes and his attempts to unify the theories of general relativity and quantum mechanics. Seife also describes much of the related research done by Hawking’s contemporaries. In search of the real Stephen Hawking.

The collaboration’s research, which combines aspects of two famous physics experiments from the past, reveals that the division of particle spins into two populations – as observed by Otto Stern and Walther Gerlach a century ago – involves pure quantum states. Interferometry advantage. A full loop.
