Topological qubits are based on exotic states of matter that are protected from local perturbations. Microsoft is heavily invested in this area, exploring the use of Majorana fermions as topological qubits.

Beyond the specific qubit technology, several key concepts are crucial for understanding what makes quantum computing work:

• Superposition: Qubits can exist in a superposition of states, meaning they can represent both 0 and 1 simultaneously. This allows quantum computers to explore multiple possibilities at once.
• Entanglement: Entanglement is a quantum phenomenon where two or more qubits become linked together in such a way that they share the same fate, no matter how far apart they are. This allows quantum computers to perform complex calculations that are impossible for classical computers.
• Quantum Gates: Quantum gates are the building blocks of quantum algorithms. They are analogous to logic gates in classical computers, but they operate on qubits instead of bits.
• Quantum Algorithms: Quantum algorithms are specific sequences of quantum gates that are designed to solve particular problems. Examples include Shor’s algorithm for factoring and Grover’s algorithm for searching.
• Quantum Error Correction: Quantum computers are highly susceptible to errors due to their sensitivity to the environment. Quantum error correction techniques are essential for protecting quantum information and ensuring the accuracy of quantum computations. Quantum Journal publishes research on quantum error correction and other topics.

The ongoing Quantum Computing Advancements are focused on improving the coherence, fidelity, and scalability of qubits, as well as developing more robust quantum algorithms and error correction techniques. The ultimate goal is to build fault-tolerant quantum computers that can solve real-world problems.
