If you are interested in quantum computing and interested in building your very own at home, you might be interested to know it’s very easy to build a quantum computer although it might not be capable of exactly what you’re hoping. To learn more about what you can expect from a DIY quantum computer and how to build your very own homemade quantum computer, check out the demonstrations below, kindly created by Looking Glass Universe.this
Quantum computing is a fascinating field that has captured the imagination of scientists and tech enthusiasts alike. Unlike traditional computers that use bits to process information, quantum computers utilize qubits. These qubits can exist in multiple states at once thanks to the principle of superposition. This unique feature allows quantum computers to perform certain calculations much faster than their classical counterparts. However, it’s important to note that quantum computing excels in specific tasks rather than serving as a one-size-fits-all solution.
One of the most talked-about abilities of quantum computers is their potential to factorize large prime numbers efficiently. This is a significant development because it poses a threat to the security of modern encryption methods. The concern over quantum computing’s impact on encryption was first raised nearly 30 years ago when a prime factoring algorithm was introduced. Despite this, the development of new quantum algorithms has been a slow process.
Homemade quantum computer
Learn more about the capabilities of a homemade quantum computer, constructed by the Looking Glass Universe, taking the form of a simple machine with just one qubit. It’s not designed to break encryption or solve large-scale problems. Instead, its purpose is to showcase the basic principles of quantum computing. One such principle is demonstrated through the Deutsch-Josza algorithm.
The Deutsch-Josza algorithm is designed to solve a particular problem: determining if a function is balanced or constant. To demonstrate this, the author uses light polarization to simulate a quantum function. The experiment relies on optical components like wave plates and filters to manipulate light polarization and encode information into the qubit.

Setting up the experiment requires overcoming challenges, especially in converting the function into a format that the DIY quantum computer can understand. Once the setup is complete, the quantum computer can solve the Deutsch-Josza problem in a single step. This is due to the inherent properties of quantum computation, such as superposition, which allows the qubit to be in multiple states at once, and interference, which combines these states to produce a solution when measured.
While the single-qubit quantum computer is not equipped for complex tasks, it effectively demonstrates the unique capabilities of quantum computing. The Deutsch-Josza algorithm shows how quantum computers can process information in ways that are impossible for classical computers. This experiment sheds light on the specialized potential of quantum computers to solve certain problems quickly, though they are not ready to take over all the functions of classical computers.
