Quantum computers have a cold problem. Today's leading machines keep their qubits a fraction of a degree above absolute zero, inside dilution refrigerators that cost a fortune and fill a room. Heat and stray magnetic fields scramble fragile quantum states, so the industry's answer has been to freeze everything.

Pune-based inventor Premchandra Jagannath Lokhande thinks there is another way. His Indian patent application 202521052092, now filed internationally as PCT/IN2026/050936, describes what he calls the DSRSS & QMPI architecture. It is meant to keep quantum phase stable at room temperature, roughly 290 to 310 K, with no cryogenics at all. 

Cancel the noise instead of freezing it 

The core idea is active cancellation. Two bifilar helical coils on copper yokes are driven in exact opposite phase at 13.56 and 27.12 MHz. Their fields cancel sideways, leaving what he describes as a quiet channel along the axis where transverse magnetic noise falls below 1.2 nanotesla. Think of noise-cancelling headphones, but for magnetic fields. Rather than draining all the energy out of the environment, the design tries to erase the specific disturbances that cause decoherence. 

Reading quantum states with light 

Readout is the second piece. Instead of electro-optic modulators, the application places a terbiumdoped optical fibre inside the chamber. Magnetic changes rotate the polarisation of light passing through it, a well-known effect called Faraday rotation, and that rotation becomes the signal. He says this removes the electronic noise that modulators add.

The numbers he claims 

According to his own published summary, the system: 

• cancels 99.9% of transverse magnetic noise

• keeps temperature drift under 0.1 K

• sustains coherence times above 100 nanoseconds

• encodes data across a 192-dimensional state space instead of simple binary 
A related filing, the DSRSS gradiometer (202521051989), uses similar coil geometry for magnetic sensing and claims 90 to 100 dB of noise rejection at ordinary temperatures. 

 

Why it matters for this community 

Whether or not this design holds up, the question it asks is the right one. If quantum hardware can work without the freezer, cost, size and access all change, and independent Indian inventors clearly want a say in that future. So here is a question for readers: what experiment would you want to see before believing a claim like this?
