![]() With the trapped ion solutions, the qubits can be measured using microwave energy. For example, ions in magnetic, electric fields are “captured” or photon quasiparticles as well as synthetic and actual atoms are used. This is where we find differing solutions. While silicon chips are normally used to process standard bits, quantum computers require new technologies. In order to make qubits useable in quantum computing they need to be created. Only when it is measured does a qubit get a defined binary state due to quantum collapse. On top of this, it could also have a wide-range of states in between such as “a third of 0” or “two-thirds of 1”. On the basis of the quantum-mechanical superposition concept, a qubit can have both the 1 and 0 states. However, qubits are not based on binary code, so they don’t need to “decide”. Bits can have a state of either 1 such as “true/on” or 0 meaning “false/off”. A bit based on binary code is the smallest data unit in digital technology. Since the first “Matrix” film, complex topics such as artificial intelligence and computer simulations have been more in the public eye and more people now understand the binary ones and zeros. So, what does that mean?įirst, we need to understand how bits work. However, this is where the similarity ends since, unlike the binary units we find in our computers today, the qubit is a quantum-mechanical measurement unit. Although quantum computers are in reality a long way away, qubits can open unlimited possibilities in performance and our understanding of computers.Ī bit does have one thing in common with a qubit: They are both the smallest computing and memory unit of their computer systems. They are also the reason why governments and companies such as IBM, Google and Microsoft have a lot of hope for quantum computing. This puts them into a defined state such as 1 or 0.Īll three principles can also be found in qubits and, therefore, quantum computing. Quantum collapse is the moment in which systems, which had previously found themselves in an undefined superposition, “collapse” when being observed or measured.If any smaller part is changed, any other part of the system connected to it will be changed as well. This is because there are two or more smaller parts which are entangled with each other and instead of having defined individual states, they create a combined system. Quantum entanglement is a phenomenon found in quantum mechanics which was described as “a spooky action at a distance” by Albert Einstein.This can be illustrated by using an example of the binary system: Instead of 1 or 0, quantum systems can have as many different states at the same time until a measurement results in 1 and 0. Superposition is a quantum system which can have two states at the same time.In order to understand how qubits work, we first need to look at the three essential principles of quantum mechanics: Qubits are defined by the two-state quantum system, i.e., they can have two states at the same time. This is different in every way from the well-known bits that we use in our computers today. Behind these cryptic values are the smallest, most basic computing units in quantum computing, “Qubits”. The future of computing has a name: - qubits.
