   - The new qubits, discovered by MIT physicists, stay in “superposition” for up to 10 seconds and could make a promising foundation for quantum computers.
   - In this state, a qubit should be able to communicate with other qubits and process multiple streams of information, to quickly solve problems that would take classical computers years to process.
   - To make a functional quantum computer using vibrating qubits, the team will have to find ways to also control individual fermion pairs.   


MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions. They found that when pairs of fermions are chilled and trapped in an optical lattice, the particles can exist simultaneously in two states — a weird quantum phenomenon known as superposition. In this case, the atoms held a superposition of two vibrational states, in which the pair wobbled against each other while also swinging in sync, at the same time.
