Quantum Information Lab · Seoha University (fictional)
We build qubits that hold their state, and the codes that protect it.
Superconducting devices, quantum error correction and the algorithms that run on them. The arrow on the sphere is one qubit — drag it.
|ψ⟩ = 0.87|0⟩ + 0.50·ei40°|1⟩

The lab in one line
Our three topics, written as a superposition. Each amplitude is the square root of that topic’s share of our papers, counted from the publication list.
Recent papers
The last twelve months, played on three wires
Each box is a paper on its topic wire; a box across two wires is a paper that spans both. The numbers match the publication list.

Make two qubits share one fate in three clicks
Place a Hadamard and a CNOT and the measurement bars split into |00⟩ and |11⟩ only — an entangled Bell pair. Our students use this page in the undergraduate course.
