Quantum Computing Without Qubits
An anonymous reader shares this interview with quantum computing pioneer Ivan Deutsch. "For more than 20 years, Ivan H. Deutsch has struggled to design the guts of a working quantum computer. He has not been alone. The quest to harness the computational might of quantum weirdness continues to occupy hundreds of researchers around the world. Why hasn't there been more to show for their work? As physicists have known since quantum computing's beginnings, the same characteristics that make quantum computing exponentially powerful also make it devilishly difficult to control. The quantum computing 'nightmare' has always been that a quantum computer's advantages in speed would be wiped out by the machine's complexity. Yet progress is arriving on two main fronts. First, researchers are developing unique quantum error-correction techniques that will help keep quantum processors up and running for the time needed to complete a calculation. Second, physicists are working with so-called analog quantum simulators — machines that can't act like a general-purpose computer, but rather are designed to explore specific problems in quantum physics. A classical computer would have to run for thousands of years to compute the quantum equations of motion for just 100 atoms. A quantum simulator could do it in less than a second."
... if you know the computer's speed, you cannot know where the computer is.
Classified information is purely a product of the government. They can't just classify information produced by citizens (citation: the first fucking ammendment, you dumbass crank).
Actually they can and have done so in the past, primarily in the field of cryptography, a field for which quantum computers might have important applications, so his fears are not unfounded.
If I can be modded down for being a troll, can I be modded up for being an orc, or a balrog?
Einstein invented quantum mechanics and you're an idiot.
He was part of the group, he opposed the idea of randomness in quantum mechanics, since he firmly believed that determinism was a fundamental property of science.
In a similar way Schrödinger opposed the idea of multiple states in quantum mechanics because of the implications it has when you apply it on macroscopic objects. The cat analogy was made to show that larger things like life and death becomes undefined if you allow a single particle to have an undefined state.
Quantum mechanics has always been controversial, even to this day.
