Real-world computers that can speedily crack even the most secure codes are within grasp thanks to recent advances that will allow for so-called fault-tolerant quantum computers, according to an expert in the field.

Quantum computers differ from classical, or regular, computers at the most basic unit of information. In classical computing, the basic unit of information is a bit: either a 1 or 0.

The science of horse racing

Secretariat was the first horse to win the Triple Crown in 25 years when he crossed the finish line at the Belmont Stakes in 1973 with a lead of 31 lengths. His time of 2 minutes and 24 seconds remains an unbroken course record. The chestnut colt also set a still-standing record at the Kentucky Derby, the first leg of the crown. A timer malfunction at the Preakness Stakes put his speed on that track in question. His unofficial time of 1:53 2/5 has been tied twice, but never beaten.

“That horse was a phenomenon,” says Kenneth McKeever, associate director of the Equine Science Center at Rutgers University in New Jersey. Now the phenomenon has been immortalized in “Secretariat,” Disney’s feel-good movie about the racehorse and his dynamic owner, Penny Chenery Tweedy.

The most feared and revered of the dinosaurs did not have the leg strength to run very fast, if at all, according to a computer model developed by two experts in the mechanical movements of living creatures.
