Recent Quantum Computing and Bulk Spin Resonance Quantum Computing Problems with current computing: • As computers get faster and smaller, limits will be reached that cannot be broken. • If computers are to continue improving, a new method of computing must be created. • Quantum Computing Problems with Quantum Computing: • Qubit • The qubits need to be protected from the environment. This way they stay in the quantum phase. • The qubits need to be coupled to the environment. It won’t be any good to have a qubit and not be able to read it. • These facts contradict each other. What do we do about it? • We know it is hard to make a quantum computer stay a quantum computer. • Two scientists, Neil Gershenfeld and Isaac Chuang have developed a new method for quantum computing that may bypass the original constraints. New method: • Don’t try to isolate separate qubits, but use a large thermal ensemble. • Apply RF pulses to the system, resonances occur and it creates a deviation from equilibrium that simulates the behavior of qubits. New method: • The spin of the particles is isolated from the environment, and can therefore last much longer than previous computers. • This means that more computations can be done before the coherence is lost. Also • Because the qubits are together in a group, the quantum state can be read. • This couldn’t be done by attempting to read the state of an individual qubit. Also • The most important part of the computer uses ordinary molecules. It is nothing new. • A source of resonance is needed, such as a Nuclear Magnetic Resonance spectrometer. • This will allow for around 10 qubits. If… • If this new method works, • The new computer could demonstrate extremely fast algorithms and quantum error correction. • New quantum states could be realized that violate Bell’s Theorem. • The computer could eventually be the size of a current desktop.
