The company has patented a structure that stacks superconducting quantum memory in layers rather than placing the components side by side. This could let the company fit more memory on the same chip.Samsung has registered a patent in South Korea under KR102778201B1 for a new superconducting qubit memory structure (via ETNews). The patent focuses on stacking multiple superconducting resonator layers vertically, so quantum memory components can occupy more of the same chip area. The company has also registered similar patents in the US (US12062826B2, US12381298B2).Quantum computers operate differently from conventional computers. Instead of using bits that can hold either 0 or 1, they use quantum bits, or qubits, which can hold both states at the same time through superposition. Samsung uses superconducting circuits to create these qubits, which depend on electrical resistance disappearing at very low temperatures.Smartwatch of your choice, up to $4999,554 entries so far.Qubits are sensitive to external interference, including temperature differences, electromagnetic noise, and vibrations. As a result, scaling quantum computers becomes harder.Join SammyGuru Rewards for free.

So, if manufacturers want to add more components, it requires a larger chip and longer connections.Samsung’s latest patent explores stacking the memory vertically. The structure uses a superconducting wiring layer, an insulating layer, and a superconducting cover layer. The company can repeat these layers to create a compact multilayer structure.The superconducting wiring and cover layers are around 50 to 100 nanometers thick. Meanwhile, the insulating layer measures around 200 to 600 nanometers. The patent also switches the cover structure between odd- and even-numbered layers.This method features more memory in the same area and keeps the layers connected. It also reduces signal distortion thanks to using the top cover to block external electromagnetic waves.However, the patent does not mean that Samsung has already created a complete quantum computer. In fact, it shows the company’s research into making superconducting qubits densely and uniformly.Written byBinay Konwar started his blogging journey in 2014 and has since written plenty of tech articles.
