Introduction to Quantum Computing
15 credits
Classical computers are based on bits, which are either 0 or 1. Quantum computers, on the other hand, use qubits, which can be both 0 and 1 simultaneously, thanks to a phenomenon called superposition. This allows quantum computers to process much more information at once. Another unique feature is entanglement, where qubits affect each other regardless of distance, enabling faster problem solving.
In quantum computers, quantum gates like the Hadamard and Pauli gates are used to manipulate qubits. Algorithms such as Shor's factoring algorithm and Grover's search algorithm demonstrate quantum computers' ability to solve problems faster than classical computers.
In fields like quantum chemistry, quantum computers can simulate molecules and calculate energies with high precision. Quantum cryptography and quantum teleportation open new doors for secure communication.
The development of physical qubits — from ion traps to superconducting circuits — is ongoing, though challenges like decoherence, where qubits lose their quantum information, require advanced error-correction techniques.
Recent advancements have improved the performance of quantum computers, and although the technology is still young, it is expected to soon revolutionize both science and industry.
Kalmar – the student city by the sea
Right in the heart of Kalmar, by the sea, you’ll find Campus Kalmar. Everything is close by, and no matter where you live in the city, you’ll be within cycling distance of the university.
If you’re a new student, you’re covered by an accommodation guarantee, meaning you have the right to student housing within two months. This is one of the reasons why Kalmar has been recognised as one of Sweden’s best student cities – several times.
The municipality has around 70,000 inhabitants. The city boasts a strong business sector, with leading companies in green industries, e-commerce, and e-health, providing plenty of opportunities to make connections for your future career.
Kalmar has a charming and historic city centre, with small shops, cafés, and gyms nestled along cobbled streets and alleyways. The coastline offers great opportunities to enjoy nature – whether you want to go for a walk, exercise, swim, or simply relax. Plus – Öland is just a bridge away.

Build your own degree
Did you know that you can combine single-subject courses to build your own degree? In this way, you can design your own degree based on your interests and the career you are aiming for. This does not apply to all courses so make sure to check with a study counsellor at the faculty. Learn more about how you can build your own degree and become unique on the labour market.
