Questions & Answers

Q: What is quantum computing and how does it work?

Quantum computing applies principles of quantum physics to try all possible solutions to a problem at the same time and then choose the best one. It relies on superposition, in which a particle such as an electron can exist in many theoretical states or configurations simultaneously but can be observed in only one state.

Q: What new breakthroughs in quantum computing are described?

Google announced that it was building a quantum computer designed by D-Wave at NASA’s Asim Research Center in Silicon Valley. Around the same time, scientists at Los Alamos National Labs revealed a secure quantum computing network that they had developed two years earlier.

Q: How does quantum computing improve communication security?

Directly reading quantum information makes it effectively unreadable, so authorized users need another way to access it. The Los Alamos system uses indirect observation: the computer interprets the quantum message and converts it into a traditional binary message, creating a one-time readable communication that is described as very safe but not perfectly secure.

Q: What is superposition in quantum computing?

Superposition is the idea that a particle, such as an electron, can exist in many theoretical states or configurations at the same time. It can be observed in only one state, and this concept helps quantum computers consider multiple possible solutions simultaneously.

Q: What do qubits do in the Google and NASA quantum computer?

The qubits can run extremely complicated programs and models very quickly. After they complete their work, the system provides the user with a comprehensible binary answer.

Q: How could quantum computing advance artificial intelligence?

Google and NASA hope quantum technology will produce major advances in artificial intelligence. The described potential includes independently tackling many-faceted problems, analyzing patterns, and recognizing shapes and voices.

Q: Why is quantum computing difficult to develop?

Quantum computers have been an idea since the 1970s, but building them has been difficult because they depend on concepts from quantum mechanics. Superposition and the problem of reading quantum information without making it unreadable are among the challenges discussed.

Q: How was D-Wave’s commercial quantum-based computer being used?

Lockheed Martin bought the first commercial quantum-based computer from D-Wave. The aerospace company intended to use it to help design jet engines and satellite systems.
