When do you think Quantum Computers will be out? Most scientists think 20-30 years but we have them in the lab already, they're just 1.5mill and only about 6 qubits.
xts said:They are already out. A month ago first 128-qubit commercialy available machine was sold for 10M$. Is it worth its price - what applications may it be really used for?
Quantum computers are not as universal like 'classical' ones. You can't write 100,000 lines of C++ code. So if the algorithm (AQO for this box) is designed for optimisation, it doesn't mean you really may find a minimum of any function you like.
Great question: what this D-Wave machine is really able to compute?
xts said:That's what I expected from D-Wave.
Anyway, even single 10M$ box in a short time for 55 people, deducting expenses, still makes something like 100k$ per head - not terribly bad ;)
10 years ago IBM claimed to fraction 15 into 3*5 (which is a special easy case for Shor's algorithm)
Did anybody make any progress since then? 21 maybe?
Should I feel safe with my 4-bit long RSA signature ?
It is difficult to predict an exact timeline for when Quantum Computers will be available for public use. Many experts believe that it could be within the next decade, but it ultimately depends on the progress of research and development.
Quantum Computers use quantum bits, or qubits, instead of traditional bits, which allow them to perform calculations and processes at a much faster rate. They also have the ability to handle much larger and more complex datasets.
It is unlikely that Quantum Computers will completely replace traditional computers. They will likely be used in conjunction with traditional computers for specific tasks that require their unique capabilities.
Quantum Computers have the potential to revolutionize industries such as pharmaceuticals, finance, and telecommunications. They can also be used for complex simulations and optimization problems.
Quantum Computers use principles of quantum mechanics, such as superposition and entanglement, to perform calculations. These principles allow qubits to exist in multiple states at once, allowing for more complex and faster processing.
