Chinese semiconductor thread II
- Thread starter vincent
- Start date
I am not an expert in hardware (so welcome any criticisms), but I think I know fairly well what is happening:
Essentially modern day compute relies on passing electricity through transistors which are physically created on Silicon based chips (though with doping to finely control properties). This has been the basic architecture for a long time, and despite there being some other architectures (like SiC and GaN for power), most have not been able to replace or even pose a threat to this silicon based architecture.
The thing is that you don't need electricity, or even Silicon to implement logic circuits. If I am not mistaken there's even this scene in Three Body Problem (or some other show?) where a computer was built using humans, which acted like transistors, all then arranged in logic gates and higher up.
So, an alternate implementation of logic can be had using photons (or light). So light would be the fundamental unit (rather than electricity) and light would be controlled using a newer equivalent to a transistor, for implementing logic circuits. This potentially can be a game changer by providing huge improvements in power consumption. However, the whole field is experimental, and silicon photonics has a LONG distance to go.
This circuit is a major progress in the field, however still a LONG way before they can be an actual replacement to Silicon-Electron based implementations of logic.
Thanks bro for explaining to us in layman terms.
Huawei patent "an amplification circuit, chip and qubit reading system" published
Huawei Technologies Co., Ltd. has published a patent for "an amplification circuit, chip and qubit reading system". The application publication date is April 5, 2024, and the application publication number is CN117833844A.
An amplification circuit, chip and qubit reading system. Applied to quantum state reading and quantum weak measurement fields. The amplifier circuit includes N series-connected lumped capacitance and inductance modules. The lumped capacitance and inductance module includes a series-connected lumped capacitance unit and a lumped inductance unit. The lumped inductance unit of at least one lumped capacitance and inductance module includes at least one superconducting quantum interference unit. The device SQUID, including the lumped capacitance and inductance module of the SQUID, also includes a pump signal line, and the pump signal line is mutually inductively coupled with the SQUID. The amplifier circuit is equivalent to an equivalent lumped capacitance module connected in series with an equivalent lumped inductance module. These two equivalent modules form a nonlinear resonator. The Q value of the coupling between the nonlinear resonator and the external environment is the impedance of the nonlinear resonator and The ratio of the impedance of the external environment. In order to form a resonant mode, the value of the capacitor in the nonlinear resonator is designed to be small, so that the capacitor can be manufactured through a planar capacitor process, thereby simplifying the manufacturing process of the amplifier circuit.

What happened to Huawei P70?
Does anyone have a DigiTimes subscription to post the article? Also, there's another news in real time section (on Digitimes) about China's chip equipment import substitution. If anyone has access and is willing to share.
Huawei P series has been renamed Pura series. Huawei Pura70 has released a trailer and will go on sale soon.
