Question about Constructing a Simple Quantum Computer

In summary, the conversation discusses the possibility of constructing a simple computer using an interferometer setup that can generate random numbers based on the quantum mechanical nature of light. The speaker asks if it is possible to analyze the stream of photons from a basic laser pointer and generate a random number based on the probability of the photons taking different paths. They also inquire about any tutorials or alternative projects related to this topic. The mention of David Deutsch's lecture series is brought up as a potential source for further information.

I was curious if it would be possible to construct an incredibly simple and most likely trivial computer based on an interferometer style setup which could generate random numbers based on the quantum mechanical nature of light. Namely, with a basic laser pointer, some mirrors, and a beam splitter, would it be at all possible to analyze the stream of photons from the laser and generate a random number based on the probability that an arbitrary photon took one of two paths?

If so, are there any good tutorials for performing such a task, specifically on reflecting the outcome to a computer to perform computations with? If not, is there some type of alternative or perhaps similar project to what I am inquiring about? Thanks again all.

Also, as a follow-up to this question, I think David Deutsch touches on this topic in the first 2 videos of his lecture series by http://www.hpl.hp.com/breweb/quiprocone/Protected/DD_lectures.htm" . Really good set of lectures by the way if any of you were interested. Not sure if this helps a bit on the elaboration side, but if not I'd be more than happy to try to explain my ideas. Thanks again.

Related to Question about Constructing a Simple Quantum Computer

1. What is a quantum computer?

A quantum computer is a type of computer that uses principles of quantum mechanics to perform operations. Unlike classical computers that use bits (0s and 1s), quantum computers use quantum bits (qubits) that can exist in multiple states simultaneously, allowing for faster and more complex calculations.

2. How does a simple quantum computer work?

A simple quantum computer works by manipulating the quantum states of qubits to perform calculations. This is done through quantum gates, which are similar to classical logic gates but operate on qubits. The qubits are then measured to obtain the final result.

3. What are the potential applications of quantum computers?

Quantum computers have the potential to significantly speed up calculations for tasks such as cryptography, optimization, and machine learning. They can also be used for simulating quantum systems, which can aid in understanding complex phenomena in physics, chemistry, and biology.

4. Is it difficult to construct a quantum computer?

Yes, constructing a quantum computer is a complex and challenging task. It requires specialized equipment and expertise in areas such as quantum mechanics, computer engineering, and materials science. Additionally, quantum computers are sensitive to external influences, making it difficult to maintain their fragile quantum states.

5. Are there any simple quantum computers currently available?

While there are no fully functional quantum computers available to the general public, there are some simple quantum computers that have been developed and are accessible for research and educational purposes. These include platforms such as IBM Quantum Experience and Microsoft Quantum Development Kit.
