What is a transmon qubit?

What is a transmon qubit?

In quantum computing, and more specifically in superconducting quantum computing, a transmon is a type of superconducting charge qubit that was designed to have reduced sensitivity to charge noise.

What is Xmon qubit?

Our `Xmon’ qubit combines facile fabrication, straightforward connectivity, fast control, and long coherence, opening a viable route to constructing a chip-based quantum computer. …

How does a superconducting qubit work?

A typical flux qubit is made by joining three Josephson junctions with superconducting leads to form a closed loop and using an applied magnetic field (perpendicular to the loop) to drive the circuit by controlling the phase (see figure 1c).

How big is a Transmon qubit?

Current transmon qubit designs consist of two small superconductive plates, about the size of a few hairs (100 microns), placed next to each other on the chip.

Can you build a quantum computer?

You really can build a quantum system using commercially available parts, and you can even control and program your device using open-source software like Qiskit.

How is qubit superconducting measured?

In the context of superconducting qubits, measurement is performed by heterodyne detection of a weak microwave probe tone transmitted across or reflected from a linear cavity that is dispersively coupled to the qubit (2–8).

Can you buy a quantum computer?

So, even they do exist, unless you have a few million dollars you don’t need, you won’t be able to buy a quantum computer today. At the same time, quantum computing is one of the most promising technologies. It is a technology you may want to start learning today rather than tomorrow.

How fast is a quantum computer?

Google announced it has a quantum computer that is 100 million times faster than any classical computer in its lab. Every day, we produce 2.5 exabytes of data. That number is equivalent to the content on 5 million laptops.
