The word quantum computers conjures up images of super-sleek, all-silicon machines that can complete complex calculations in seconds. In fact, many of these computers are built with the help of superconducting quantum devices (SQUIDs). These devices offer a number of benefits over conventional electronic circuitry: They're extremely fast, allowing for faster calculation times; they're small and light so they can be easily incorporated into other devices; and they require very little power to function. Because of these benefits, SQUIDs are widely used in modern computers. However, while they provide some great advantages over regular electronic circuits, they aren’t enough to build an advanced quantum computer. That’s where the help of semiconducting nanomaterials comes in. The right nanomaterials can both augment and replace conventional circuits enabling you to build a more advanced machine without resorting to using SQUIDs.

What is a quantum computer?

A quantum computer is a computer that uses quantum mechanics, the study of the properties of electrons and other subatomic particles, to predict and calculate the results of operations on these particles at a much more detailed level than is possible with conventional computing. Current conventional computers are based on binary notation, which only allows for calculation in two states (on or off). To perform more advanced calculations, such as those needed to solve complex mathematical problems, a quantum computer uses superposition states, in which the particles are in multiple states at the same time. A typical computer requires power to function, and in a quantum computer, power would be distributed among the many parts that make up the machine, rather than being concentrated in a few parts that perform the majority of the operations.

How to build a quantum computer

Like all computers, a quantum computer can be built in many different ways. For example, an individual qubit could be built into a single Lego brick or a single atom could be used to represent a qubit. The main building blocks for a quantum computer are qubits or quantum bits, which are the unitary states that represent the states of a quantum computer. In order to build a quantum computer, you need a qubit, a measuring device to determine its state, and a computer to hold the information created by the qubit. The building blocks of the qubit are often called bits or particles. A single bit might represent 0 (or no state) and another bit could represent 1 (or yes) or some other value.

Why use nanomaterials to build a quantum computer

The benefits of using nanomaterials to build a quantum computer are many. These include: Ultra-compact and inexpensive - Nanomaterials have been used in computer chips for years, and are inexpensive and easily integrated into devices. It’s easy for researchers to integrate these materials into computers.

Nanomaterials that can boost your machine

In order to build a more advanced machine, you need to make use of the capabilities of the nanomaterials that are already present in your device. Nanoparticles can be used to add functionality such as extra memory, faster processing power, or increased diagnostic capability. Additionally, due to their small size, they could be used to improve the resolution of a camera or the range of a radio frequency identification (RFID) device.

Nanomaterials that can replace your machine

In order to make your device more advanced, you will also need to replace some of the nanomaterials that are present in your prototype machine. This is where nanotechnology comes in. You can use nanotechnology to “replicate” some of the properties of the original nanomaterials, adding even more functionality to the device. For example, you could use carbon nanotubes to create a more conductive environment and use sulfuric acid to create a strong pH that would be difficult for bacteria to survive in.
