The Quantum Battle Dome: IBM Versus Google
Ladies and Gentlemen, Girls and Boys: Behold The Quantum Battle Dome, occupied by opposing Quantum Computational Devices. On the left, appears Sycamore - Google Inc.'s (NASDAQ: GOOGL) quantum computational construct and on the right, you'll see the quantum device monikered Summit, carefully crafted by IBM Corporation (NYSE: IBM). All of this, via the expert commentary of Kevin Hartnett, writing at Quanta Magazine. Enjoy.
Quantum Of Tuesday: Google Quantum AI's Paper, Whereabouts Known
via Bianca Bharti - writing for Canada's National Post, comes news of Google, Inc's (Nasdaq: GOOGL) stunning accomplishment in quantum computation. Described in a paper entitled 'Quantum supremacy using a programmable superconducting processor' and published at NASA (since taken down, but, available here, along with a bibliography document entitled 'Google Quantum Supremacy (Supplementary information) 09-2019' here.). Read it and weep for the quantum advertising onslaught from Serge and Larry coupled with the complete demise of your future self's privacy in all alternate universes...
"The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamen- tal challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits, occupying a state space 253 ∼ 1016. Measurements from repeated experiments sample the corresponding probability distribution, which we verify using classical simulations. While our processor takes about 200 seconds to sample one instance of the quantum circuit 1 million times, a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task. This dramatic speedup relative to all known classical algorithms provides an experimental realization of quantum supremacy on a com- putational task and heralds the advent of a much-anticipated computing paradigm." - via the Google AI Quantum and collaborators, et al - enumerated within the paper here**

Quantum Computation, The Looming Dish of Doom
via Martin Giles, writing at the MIT Technology Review, comes word from the National Academies of Sciences, Engineering and Medicine of Looming Quantum Doom (currently scheduled within 20 years). Good News, eh?
'The experts who produced the report, which was released today, say widespread adoption of quantum-resistant cryptography “will be a long and difficult process” that “probably cannot be completed in less than 20 years.' - via Martin Giles, writing at the MIT Technology Review
Quantum of Saturday →
via Philip Ball writing at Quanta Magazine - the web-based publication of the Simons Foundation - comes this superb piece on the current state of quantum computation, and the - apparently - rather long road ahead. Certainly, a Saturday Must Read!
