The decoherence time, which is the duration a qubit can maintain its quantum state, is crucial for quantum computing, with ion traps achieving significantly longer coherence times compared to other methods.

The key to effective quantum computing is ensuring qubits interact as desired, rather than just focusing on increasing coherence times.

We can create qubits that are entangled at 90% quality, but we can store them practically forever, allowing us to enhance their quality through a process similar to improving a staticky communication channel.

Achieving high fidelity in qubit operations is crucial; the Oxford team has reached a fidelity of 99.9%, which is essential for reliable quantum computing operations.

The ability to perform hundreds of thousands of operations per second in quantum computing means that even a short decoherence time can be sufficient for many calculations.

The threshold for effective quantum computing has improved to around 99% fidelity, meaning that if a quantum computer operates correctly 99% of the time, it can effectively manage errors and perform complex calculations.

Qubits, the building blocks of quantum technology, are inherently unstable and tend to collapse to a single state, making them difficult to control compared to classical bits.

In quantum computing, the challenge is to keep qubits isolated to prevent decoherence, which can be achieved through various techniques, including using vacuum chambers and ion traps.

A qubit, which represents a property of particles called "spin," can exist in a superposition of states, unlike classical objects that are either one state or another.
