New records in quantum computers.

New quantum computers require photonic circuits to transform binary data into qubits. And also, those systems can help to control the energy use of quantum computers, and their temperatures are lower. The new quantum photonic microchip connects the light-emitting molecules. With single-mode waveguides. The photonic microchips are halfway to compact quantum computers. Photonic chips can make. New types of observation tools are being brought into reality. Things like quantum Doppler radars, where two photons orbit each other. Those photons are in quantum entanglement with other photons that are connected to the system. Two rotating photon pairs can scan the atom’s internal structures. They act like miniature Doppler radar. 

The 50-qubit quantum computer was simulated for the first time. And the Princeton researchers set a record for qubit sustainability. Those things are a big step for quantum computers. The problem with quantum computers is their ultimate power. Regular binary computers need even tens of billions of years to solve problems that the quantum computer solves in minutes. This makes it hard to create error detection for quantum computers. This record was set by using a supercomputer.  That uses an NVIDIA-chip-based architecture.

The quantum computer requires simulations to create the superpositions and quantum entanglements that those systems need. Then the system makes those connections between photons. And the weakness is that. A quantum computer is much more sensitive to outside effects. Than regular electronic computers. The biggest problem with high-power electronic computers is their heat. The simulation must be delivered to the system that maintains and controls the quantum computer. And the thing that makes quantum systems complicated is that. 

Theoretically, it is possible to make static quantum entanglement. Using some ball-shaped particles. The system puts those particles into spin motion. The idea is that. They send the string from their spin axle to the receiving particle’s equator. Then receiving particle. Starts to oscillate. And send that wave movement from its spin axle or “pole”.  

Then the quantum string transports that data to the next particle’s equator. And that can form a complex quantum system. There are quantum entanglements. That forms the box-shaped structures. Those systems are hard to control. 

The system uses those simulations for adjusting the quantum computer’s internal functions. And the problem is that things like earthquakes, cosmic rays, high-energy bursts, or even gravitational waves could disturb those systems. Those non-predictable effects can cause situations. That the system makes mistakes is hard to predict. The effect can be the situation. There, the car impacts the building, where the quantum computer is. Those things make quantum computers untrustworthy in some situations. It’s impossible to predict all variables that can affect the qubit.
