# Sound vibrations can encode and process data like quantum computers do

Another obstacle to development is that a quantum computer operating at the scale needed to deliver significant breakthroughs will require potentially millions of qubits to be connected. The few quantum computers that exist today are nowhere near that number. Digital computers have been making it easier for us to process information for decades.

The quantum computing industry isn’t putting all its eggs in one basket. Various designs include trapped ions, superconducting circuits, neutral atoms, electrons on semiconductors and photonic qubits. Google’s captured attention with its “quantum supremacy” announcement in 2019, in which its machine outpaced conventional computers on an academic task that didn’t actually accomplish useful work. John Preskill, a Caltech physicist who’s long championed quantum computing, has warned repeatedly about hype.

Though quantum-supported machine learning may soon offer some commercial advantages, future quantum computers could take AI even further. Quantum computers’ abilities to parse through massive data sets, simulate complex models, and quickly solve optimization problems have drawn attention for applications within artificial intelligence. Rattled by the profound risks posed by quantum computers, a number of players are moving to make blockchain tech safer. Financial analysts often rely on computational models that build in probabilities and assumptions about the way markets and portfolios will perform.

Without it, we would not have such marvels as atomic clocks, computers, lasers, LEDs, global positioning systems and magnetic resonance imaging, among many other innovations. For instance, eight bits is enough for a classical computer to represent any number between 0 and 255. But eight qubits is enough for a quantum computer to represent every number between 0 and 255 at the same time. A few hundred entangled qubits would be enough to represent more numbers than there are atoms in the universe. Quantum computers are machines that use the properties of quantum physics to store data and perform computations.

### Experiments Show Quantum Computers Can Be Better Than the Sum of Their Parts

Although there is no urgent cause for alarm, sophisticated actors with the ability to harvest encrypted data will eventually (nobody knows exactly when) be able to decrypt that information with quantum computers. As such, industry experts are promoting a proactive approach to quantum-proof encryption to protect any data that might still be useful to hackers years after they collect it. It is still unclear which physical system will constitute the quantum bits that can be utilized quantum-mechanically inside the quantum computer.

## How far off are quantum computers?

Running algorithms on a quantum computer involves directing the evolution of these superposition states. The quantum rules of this evolution allow the qubits to interact to perform computations that are, in practical terms, impossible using classical computers. One major obstacle to the advancement of quantum computing is that qubits are volatile. Whereas a bit in today’s computers can be in a state of either one or zero, a qubit can be any possible combination of the two. When a qubit changes its status, inputs can be lost or altered, throwing off the accuracy of the results.

Qubits can also be inextricably linked together using a phenomenon called quantum entanglement. The result is that a series of qubits can represent different things simultaneously. Maniscalco is just one of many who think that the first commercial applications of quantum computing will be in speeding up or gaining better control over molecular reactions.

In the meantime, those running blockchain projects will likely be keeping a nervous eye on quantum computing advancements. A number of financial institutions including RBS, the Commonwealth Bank of Australia, Goldman Sachs, Citigroup, and more, have invested in quantum computing startups. Merck’s venture arm, for instance, participated in Zapata’s $38M Series B round in September. Meanwhile, Biogen partnered with quantum computing software startup 1QBit and Accenture to build a platform for comparing molecules to help speed up the early stages of drug discovery.

### Quantum physics

Quantum computers perform calculations by manipulating qubits within a register. There are various kinds of physical operations that can be performed on qubits. A binary digit, characterized as 0 or 1, is used to represent information in classical computers. When averaged over both of its states (0,1), a binary digit can represent up to one bit of Shannon information, where a bit is the basic unit of information. However, in this article, the word bit is synonymous with a binary digit. Some firms are so optimistic that they are even promising useful commercial applications in the near future.

## Classical vs Quantum

Shor’s algorithm makes it possible for a powerful quantum computer to break RSA encryption. This is the encryption that is widely used when we send data on the Internet. Researchers would need millions of qubits to compute “the chemical properties of a novel substance,” noted theoretical physicist Sabine Hossenfelder in the Guardian.
