It was 25 years ago when R. Feynman published his inspiring paper about quantum computers. At that time it was just an intriguing idea - far from any experimental implementation. Since then a remarkable progress has been made, which can be seen for example in today's computer technology. Thanks to continuous miniaturization of microelectronic circuits, sizes of elements have already reached sub-micrometer scale and according to general tendency in next 10 years the microelectronics on-chip components will reach tens of nanometers scale. At this size the physical description changes from classical to quantum physics laws. It is envisioned that future electronic circuits will consist of quantum dots connected with quantum wires. Due to these revolutionary changes of the paradigm not only does it change the principles of operation but also offers new practical opportunities. The most challenging of them is quantum computer, which is theoretically predicted to be superior to classical one for solving certain problems such as secure encryption, factoring of large numbers, data base search, and others.

25年前，R。费曼发表了关于量子计算机的鼓舞人心的论文。 当时，这只是一个有趣的想法-远离任何实验性的实施。 从那时起，已经取得了显着的进步，这可以看出，例如在今天的计算机技术。由于微电子电路的不断小型化，元件的尺寸已经达到亚微米级，并且根据未来10年的总体趋势，微电子片上元件将达到数十纳米级。 在这个尺寸下，物理描述从经典物理定律变为量子物理定律。 据设想，未来的电子电路将由量子点与量子线连接组成。 由于范式的这些革命性变化，它不仅改变了运作原则，而且提供了新的实践机会。 其中最具挑战性的是量子计算机，理论上预测它在解决某些问题方面上级经典计算机，如安全加密，大数因子分解，数据库搜索等。
