Quantum Computer
The Quantum Computer is used together with the Research Station to progress further in the game. It is first required in UV-tier to obtain the Data Stick required for the UHV-Mainframe. As TecTech multiblocks, they come with support for Laser-Hatches and Power Pass. The general idea is that the Research Station requires both power and computation packets to scan an item into a Data Stick. The computation packets are generated by Quantum Computers and sent to the Research Station via Optical Fiber Cables.
Construction
For general construction use the Multiblock Structure Hologram Projector. Holding multiple projectors in one stack will display longer versions of the Quantum Computer.
The Quantum Computer has a variable size, ranging from 5 to 16 blocks long. When holding a single Multiblock Structure Hologram Projector, it will show the shortest version with only 2 Computer Racks, however the slice with the Computer Racks can be repeated up to 12 times for a total of 24 Computer Racks. It also needs an Uncertainty Resolver, a Maintenance Hatch, Energy Hatch, and Optical Master Connector to send computation packets to the Research Station. An Optical Slave Connector may also be attached to receive computation packets from other Quantum Computers as part of a chain. Only one Research Station is needed for any number of Quantum Computers. The Optical Connectors need to be connected with Optical Fiber Cables.

By default, the Quantum Computer requires 1A UV + (1A UV per rack) to work. The power is constantly consumed regardless if anything is being researched so it is highly suggested to turn the multiblock off when not in use. An easy way to accomplish this is by attaching a wireless item detector cover to the object holder of the research station and have that turn on the quantum computer(s) via a wireless redstone receiver (internal) and machine control cover.
Uncertainty Resolver
After repairing any maintenance issues, the next step is to solve the puzzle in the Uncertainty Resolver. This is required for the machine to operate. The interface has a Schrödinger-Matrix in the middle as well as two sets of 8 buttons on the left and right. Clicking on one button and then another will switch the states of the two corresponding cells in the matrix. This means switching their blinking speed (in the basic Uncertainty Resolver) or their shade/color (in the Uncertainty Resolver X). The goal of the puzzle is to balance the states of the matrix around the glowing LED lights, turning all of them green.
The number of LED lights increases with the length of the quantum computer and reference a specific part of the matrix. The top-left LED looks at the four cells in the top-left corner while the center LED looks at the entire matrix, for example. The figure below can be used as a reference for balancing a matrix. The mode refers to the number of glowing LED lights and the numbers are the cells that should have the same or very similar states. All 1's should have the same blinking pattern or shade/color as should all 2's and so on.
Despite appearing as a maintenance issue, uncertainty resolvers CAN be wall-shared by multiple Quantum Computers. This means only one matrix needs to be solved for every four machines (at best), saving a bit of time and resources. The Uncertainty Resolver X is also significantly more stable than the basic version in that all cells tend towards the same state over time, essentially solving the puzzle itself and preventing future issues.
Computer Rack
Now it is time to insert components into the Computer Racks. Circuits generate both computation packets and heat while vents dissipate heat. There are only four slots in each rack so there are not very many options for setups compared to a Nuclear Reactor, but the idea is the same. Every rack is completely independent from every other rack which means it's not possible to have one rack with all circuits and another with all vents. Therefore, it is highly recommended to use the exact same setup for every rack.
The computation of a rack is the sum of all the computations of the components within. For example, three Ultimate Crystal Computers and an Advanced Heat Vent generate a total of 26 + 26 + 26 + 0 = 78 computation per second. More computation means faster scanning of items into Data Sticks by the Research Station. Computation of racks can be increased with Overclocking and Overvolting.
The heat of a rack is a value between 0 and 10,000 and is reported in the interface of the Quantum Computer. The portable scanner can also return the heat level but does so as a percent out of 10,000. Every component has a certain heat limit which if exceeded will void that component. Breaking or wrenching a rack while it is hot (thermometer is lit) similarly voids the components inside. Every component also comes with a heat factor and heat coefficient which are used to calculate how much heat is added to the rack every second. Unfortunately, these values are not obvious and the math is rather complicated. Therefore, use this script to see where the heat will converge as well as other important information regarding your setup.

Stable Setups
Here are a few stable combinations of circuits and vents (last tested on GTNH 2.6.0) that should maximize computation depending on your available resources. Note that the current best setup is available to you as soon as you build your first Quantum Computer. The computation here is per rack so a full length Quantum Computer can produce up to 27,456 computation per second.

Overclock and Overvolt
The Quantum Computer features two additional configurable parameters, Overclock and Overvolt, to significantly change both the computation and power consumption of each rack. By default, both are set to 1 but can easily be changed in the interface of the Quantum Computer (LED buttons). The total power consumption of the Quantum Computer can be modeled as follows where 524,288 = 1A UV
Computation is slightly more complicated. At best, it will follow this relationship, but that assumes no packet loss (which requires a certain Overvolt to Overclock ratio).
A good rule of thumb is to follow the equation provided. Sample calculations are in the table below. If the Overvolt is any lower than these values, there will be packet loss and the Quantum Computer will be spending more power for significantly less performance. If the Overvolt is any higher than these values, you are wasting power without any boost to computation. Below 1.0, this relationship is no longer true and Overvolt should be greater than or equal to Overclock.
| Overclock | Overvolt | Power Multiplier |
|---|---|---|
| 0.80 | 0.80 | 0.64x |
| 1.00 | 1.00 | 1.00x |
| 1.50 | 1.75 | 2.63x |
| 2.00 | 2.50 | 5.00x |
| 2.50 | 3.25 | 8.13x |
| 3.00 | 4.00 | 12.00x |
Note that reducing Overclock and/or Overvolt below 1.0 actually reduces the power consumption quite nicely, but there is a limit. An Overvolt below 0.8 will start to drop packets and an Overvolt below 0.7 will drop all packets.
WARNING: Changing either Overclock or Overvolt will also have an impact on heat, as represented by the simplification below. The actual math is quite complicated so just use the script to guarantee the safety of an untested Quantum Computer setup.
